Recently, I have been working extensively with LLM-powered coding assistants - Claude Code, Cursor, Windsurf - and I noticed a frustrating pattern. Every time these tools run a command for me, they're processing massive amounts of irrelevant log output. You know how it goes - the LLM runs npm run build for your React app and receives screens full of webpack configs, browserslist warnings, and compilation progress when all it really needs are those few error lines to help you debug. But what if we could change that? What if there was a way to make every command output exactly what the LLM needs to see? Let's have a look at what I mean. Here's what happens when your LLM assistant runs a typical React build: > npm run build:graphql && react-router typegen && tsc && react-router build > buil…  ( 11 min )

If you’ve worked with GitHub Actions before, you’ve probably pulled in a bunch of ready-made steps from the Marketplace. That’s awesome for common needs like setting up Node, caching dependencies, or deploying to cloud providers. But what about those repetitive, project-specific steps that aren’t worth publishing to the whole world? That’s where local GitHub Actions shine. A local action is a custom GitHub Action that lives inside your own repository. Unlike Marketplace Actions, they’re not shared publicly—just tailored helpers your workflows can use again and again. They live under the special .github/actions/ directory in your repo: .github/ actions/ bootstrap-node/ README.md (optional) action.yml From here, you can call them in any workflow as if they were publishe…  ( 7 min )

In the world of Data Engineering, two terms come up all the time: ETL and ELT. While they sound similar, they represent two different approaches to moving and transforming data. Understanding them is essential for anyone stepping into data engineering. ETL = Extract → Transform → Load Extract data from source systems (databases, APIs, logs). Transform it (clean, filter, aggregate) into a usable format. Load it into a data warehouse for analysis. 🛠️ Example: Traditional systems like Informatica, Talend, and SSIS rely heavily on ETL. Best for: When transformations are complex and need to be done before storage. ELT = Extract → Load → Transform Extract data from source systems. Load it directly into the data warehouse or lake. Transform it there, using the power of the warehouse itself. 🛠️ Example: Modern cloud warehouses like Snowflake, BigQuery, and Redshift support ELT. Best for: When storage is cheap and scalable, and transformations can be pushed downstream. Aspect ETL 🛠️ ELT ☁️ Process Order Transform before storage Transform after storage Best For On-premise systems Cloud-based warehouses Speed Slower for big data Faster, uses warehouse compute Flexibility Limited scaling Highly scalable & flexible Choosing between ETL and ELT depends on your infrastructure and use case. Legacy systems still depend on ETL. Modern cloud-first companies lean toward ELT for flexibility and scalability. 👉 The key takeaway: Data Engineers must understand both approaches — and know when to apply each. Whether it’s ETL or ELT, the goal remains the same: make data clean, reliable, and analytics-ready. The real power lies in using the right approach at the right time.  ( 6 min )

🐉 HYDRA: How I Turned a $1000 prize Competition Entry into a FREE Open-Source Tool TL;DR: Started building for a competition that required expensive tools (n8n + Bright Data), said "screw that," and rebuilt everything to be 100% FREE.

Y’all ever write a line of code so clean, so efficient, so unnecessarily cool that you just sit back and stare at it? 😮‍💨 That’s the vibe we’re bringing today. These JavaScript one-liners aren’t just efficient—they straight-up slap. But wait! My awesome friend Gemini (yes, the AI) read this and dropped some knowledge. So we're making it even better: keeping the fun, fixing the flaws. Let’s get into it. const isAtBottom = () => window.innerHeight + window.scrollY >= document.body.offsetHeight; When you need to know if they’ve scrolled all the way down to your 4AM novel-text.

The developers are living in an exciting time. A whole new generation of AI-powered terminals, code editors and IDE plugins has emerged, promising to supercharge our productivity. They can write boilerplate code, explain complex algorithms and even debug for us. Many of these tools are free and open-source, making them incredibly tempting to install and try out. But in my role in security operations, I've seen the other side of this magic. I've watched as these "helpful" assistants inadvertently become data exfiltration channels, leaking sensitive company information directly from a developer's machine. The scary part? The developer is almost always completely unaware it's happening. This isn't about some malicious malware. The leak is often a core function of the tool itself. Let's break …  ( 10 min )

Today we're going to see how to start with a basic AI chatbot and add in tools and custom UI components. For this tutorial we'll add a "music search tool" and a "music miniplayer" to give a chatbot musical abilities in about ten minutes. But first, here's quick demo: (Link to the code: jamesmurdza/my-music-player) We'll start by creating a new Tambo app (Tambo is an open source generative UI framework): npx tambo create-app my-music-player cd my-music-player npx tambo init Once you have your Tambo project set up, you can delete a few of the template files from the example: rm src/components/ui/card-data.tsx src/services/population-stats.ts We'll be using the Deezer API to search for music, so let's define a few types which we'll use later.

Decentralized Physical Infrastructure Networks (DePIN) are quickly moving from concept to production. By linking crypto incentives to real-world devices, whether GPUs, sensors, hotspots, or vehicles, DePINs extend blockchain utility beyond pure finance. For developers, this is exciting territory: you’re no longer just writing smart contracts for token swaps, you’re orchestrating networks that process real-world data streams. But there’s a catch. With physical infrastructure comes sensitive data, and DePINs are only as strong as the privacy guarantees they provide. Let’s dive into the challenges and technical approaches. Most DePIN stacks have three layers where privacy risks surface: Payments on Transparent Chains Most DePINs use public blockchains like Solana or Ethereum for incentives. E…  ( 7 min )

Part 4 of building Additional Context Menus - where I share the war stories, 3 AM debugging sessions, and breakthrough moments that almost made me quit (but didn't). Every developer needs to hear these stories. Building this VS Code extension was 10% inspiration and 90% debugging edge cases I never imagined existed. From a 601KB bundle that made users cry, to writing 37 tests to catch bugs that only happened at 3 AM, to the philosophical crisis of AST vs Regex parsing. But hey - the breakthroughs made it all worth it! ⚡ Picture this: I'm finally ready to ship v1.0. I run npm run build and see: ✅ Build complete: 601KB bundle 601KB.

Mastering Prompt Design for Smarter AI Assistants in 2025 AI assistants are no longer a futuristic concept—they’ve become integral to how we code, work, and interact with digital tools. From GitHub Copilot to ChatGPT and beyond, their ability to provide accurate and context-aware responses depends heavily on how prompts are crafted. In 2025, prompt design has evolved into a critical skill for developers, startups, and enterprises. Let’s explore why it matters, how you can refine it, and what pitfalls to avoid. AI models are smarter, but they’re also more context-sensitive than ever before. A vague prompt produces vague answers. Meanwhile, a well-structured prompt delivers precise, actionable insights. For example: ❌ “Explain Python.” ✅ “Explain Python’s async/await feature with …  ( 7 min )

AI agents are shifting from passive assistants to autonomous actors. They can now trade, moderate communities, run social accounts, and even negotiate on behalf of users. But with this “agentic shift” comes a major roadblock: privacy. Traditional AI agents need access to sensitive data (API tokens, strategies, personal context). On the other hand, blockchains, our go-to for decentralization, are fully transparent. This clash creates what I call the Privacy Paradox of AI agents. How can we make agents private, trustworthy, and verifiable without sacrificing decentralization? That’s where the ROFL framework by Oasis and its rofl.app marketplace come in. Let’s take two common examples developers experiment with: AI Telegram Chatbots Use BotFather tokens + APIs for automation. AI models (NLP /…  ( 7 min )

Hello, I'm Maneshwar. I’m building LiveReview, a private AI code review tool that runs on your LLM key (OpenAI, Gemini, etc.) with highly competitive pricing -- built for small teams. Do check it out and give it a try! Moving a server — whether it’s to a new VM, a different provider, or fresh hardware — feels simple until something goes wrong. A missing backup, an overlooked DNS TTL, or an untested restore can turn a routine migration into an outage. Here are the essential steps you should always take before moving a server. Full system backup: Image or snapshot the disk (provider snapshots, rsync, dd, or tools like Velero if Kubernetes). Service-level backups: Dump databases (pg_dump, mysqldump), export configs (tar /etc/), and archive important app data. Verify: Try restoring a databas…  ( 7 min )

The Secret Project Although we've shared occasional updates, we've actually been quiet for a while. The reason is something every business must face: filing the annual tax return. Since it's our first year and we don't have an in-house accountant, I had to study the process myself to ensure everything was done properly. In the end, we filed the return with a registered accountant, but the legwork and learning fell on me. It turned out to be a very personal, and at times painful, journey. I'll publish separate posts diving deeper into the details and strategies we used. For now, this log highlights the key hurdles, challenges, and concepts I've encountered. From both the perspective of running the business and searching for accountants, I realized there are essentially four distinct servi…  ( 11 min )

When you deploy a smart contract on Ethereum or Solana, everything is public: contract state, inputs, outputs, even function calls. That transparency is great for auditing, but it kills privacy and limits what developers can build. That’s where Trusted Execution Environments (TEEs) come in. And more importantly, that’s where Oasis has built an entire developer stack around them: Sapphire → the first confidential EVM (Ethereum-compatible, but private by default) ROFL → Runtime Offchain Logic, for trust-minimized offchain compute (AI, heavy logic) Oasis Privacy Layer (OPL) → plug-and-play privacy for any EVM chain This post walks through why TEEs matter, and how Oasis is making them usable for developers who want to build confidential DeFi, private agents, and AI-powered dapps.

As a front-end developer, picture yourself dealing with a serious bug that makes the whole program crash. There is a lot of pressure, and the answer needs to come quickly. When things get tough like this, your best tool isn't just technical knowledge; it's deductive reasoning. You gather information, follow logical procedures, and come to a conclusion that solves the problem, just like a detective would in a mystery. This lecture covers how deductive reasoning helps developers to build, debug, and design better software—and how it parallels the way humans reason in everyday life. Deductive reasoning is a logical process where conclusions are drawn from proven premises. In programming, this entails employing known truths—like system requirements, code behavior, or user expectations—to m…  ( 7 min )

Ethics in Artificial Intelligence? Let's not fool ourselves, the game has changed and I have no doubt about that, so let's reflect a bit on this subject. I recently participated in a presentation given by the LinkedIn News Event presented by Ana Prado and the special guest, the distinguished Teacher Dr. Alvaro Machado Dias"Risks and ethical limits in the use of artificial intelligence" . It was very interesting and made me reflect a little more on this provocative and complex issue that often goes unnoticed by those of us who work directly with technology on a daily basis. It's curious how certain topics awaken in us that almost uncontrollable urge to think a little beyond, to go deeper, to open the mental "sublime" and start coding ideas as if they were lines of Go code or any other lan…  ( 11 min )

In this small article I’ll describe the simple script I’ve created while working on the Cartoon Lighthouse live wallpaper. You can find a live web demo of this app here and take a look at its source code here. I’ve encountered a slight problem with encoding 31 textures into ASTC format. The thing is that usually in all our apps geometries are batched and merged to reduce the amount of draw calls. So typically we use a couple of large texture atlases for all geometries. In this scene however geometries were not batched and I decided to keep this as is since the total amount of draw calls is still rather small (around 30). So this resulted in 31 textures which were to be converted into ASTC format. So usually I just encoded textures with some ASTC block sizes (4x4, 6x6, 8x8 and 10x10) and ma…  ( 7 min )

How AI-Driven Product Development Is Replacing MVPs, Accelerating Market Validation, and Unlocking Rapid Growth Over the last decade, the Lean Startup method has become foundational. Its approach helped founders reduce risk and conserve resources. The logic made sense at a time when building products involved substantial investment. But that environment has disappeared. AI technology has rewritten the rules entirely. Tech founders relying on the original Lean Startup methods risk becoming irrelevant. I’ve observed this shift firsthand, advising dozens of independent consultants, technical leaders, and founders. Strategies that once brought early traction now inhibit scale. Lean Startup principles, though well-intentioned, often slow founders down in today’s context. A new system is necessa…  ( 8 min )

Member-only story You got the degree, built the GitHub, earned the certs, but the ladder seems gone. The dev job market now crowns AI stars and sidelines everyone else. Last week, a friend showed me his rejection tracker: 117 jobs applied in four months. Three side projects shipped. Two AWS certs completed. One callback. And the kicker? The “junior” role required 2+ years of Kubernetes experience. He laughed, then he cried, then rage-posted. That’s not an isolated story. It’s the new baseline for dev careers. If you’re reading this right now, you’re probably scrolling LinkedIn, Reddit, or Slack in between pretending to debug something.

Stop hand-running Firebase CLI every time your schema changes. Wrap Data Connect codegen behind a single dev command and CI workflow that regenerates, tests, and publishes SDKs automatically. You know that sinking feeling when your Firebase schema changes and suddenly every PR is a roulette wheel of “who forgot to run codegen this time”? It’s like playing whack-a-mole with your CLI except the mole always wins. The good news: you don’t actually have to babysit the Firebase CLI. With a tiny wrapper, pinned tooling, and a clean CI pipeline, you can turn SDK generation into a zero-touch process. Locally, you type one command (pnpm dc:gen). In CI, everything else just… happens.

From online forms to credit scores, today’s systems do not give orders. They make you obey without a word. That difference matters. For most of history, obedience meant following an order. Someone spoke, someone else obeyed. A general said march, a judge said pay, a boss said deliver. You could disobey, even if that choice had a cost, because there was an order to refuse. Digital society works differently. Many of the rules you follow are not spoken. They are built into forms, scores, and automated decisions. You do not hear a command. You meet a structure. This is the quiet shift that defines our time. Authority used to be visible. Today it is silent. It hides in code, checkboxes, scoring models, and validation rules. The result is a new kind of obedience, one that arises because the sys…  ( 11 min )

The WAL(Redo log) is essential to normal database operations. In some sense "The LOG is the DATABASE" has some truth to it. The WAL stores a log of all activities performed in the database. In other words, it maintains the state of the database system. Having the WAL is useful in many ways and one of the most important role is in replication. Replication in Postgres makes significant use of the WAL when copying data changes from one database server to another. Every data change, once committed is replicated to all configured standbys from reading the WAL. It is important that the WAL is stored durably and long enough for new changes to be replicated to standbys. Postgres aims to be as resource efficient as possible. WAL files can build up quickly and if not well managed can fill up avail…  ( 12 min )

Error handling in APIs can get pretty messy, right? Whether it's throwing exceptions for "expected" situations like “User not found,” or dealing with ambiguous null values, traditional error handling approaches often leave us with more questions than answers. But don't worry—there's a better way! Imagine you're a waiter taking orders: if a customer orders a dish that’s not available, you don’t throw a tantrum or drop everything in the kitchen (throw Exception). Instead, you let them know it’s not available and suggest something else. Same idea applies to your API! In this post, I’ll walk you through how the Discriminated Union pattern (using a ServiceResult type) can simplify your error handling, making your code more predictable and easy to maintain.

When we study statistics, we often hear about Type 1 and Type 2 errors. But in real life, especially in medicine, these errors are not just theoretical—they can literally mean the difference between life and death. Understanding where to trade off these errors is crucial for doctors, public health policymakers, and even patients making informed decisions. Type 1 Error (False Positive): This occurs when we conclude that something is true when it is actually false. In medical terms, it’s diagnosing a patient with a disease they don’t have. Type 2 Error (False Negative): This happens when we fail to detect something that is true. Medically, it’s missing a diagnosis for a patient who actually has the disease. The trade-off between these errors often feels like a tightrope walk. Reducing one ca…  ( 7 min )

FlowiseAI is an open-source visual tool that lets you design, test, and deploy AI agents with a drag-and-drop interface. Think of it as the missing layer between raw APIs like OpenAI or Anthropic and your end-user applications. Why FlowiseAI? - Visual builders: Create workflows using Assistant, Chatflow, or Agentflow depending on how complex your agent is. - RAG-ready: Upload PDFs, Excel files, or any dataset and build retrieval-augmented generation (RAG) bots with ease. - Extensible: Integrates with 100+ tools, vector databases, APIs, and memory modules. - Production features: RBAC, observability, audit logs, and SSO/SAML …  ( 6 min )

Schema design, indexing tricks, and performance wars what devs actually care about when picking their database fighter. If databases were video game characters, Postgres and MySQL would be those two rivals you always pick just to trash-talk your friends: the tanky but flexible mage (Postgres) vs the fast, reliable brawler (MySQL). Both can sling JSON now, but the way they do it changes how you design schemas, how you write queries, and even how your app scales. The “event” that sparked this showdown? JSON isn’t just a hack anymore it’s a first-class citizen in both Postgres and MySQL. Postgres came in hot with jsonb (binary storage + magic operators) and an entire family of advanced indexes. MySQL fired back with its native JSON type in 5.7.8 and leaned on InnoDB’s ACID reliability. Sudde…  ( 12 min )

So, here's the thing... I haven't been able to build any projects and do anything meaningful because of the continual distractions. I decided that it has to change. No more chasing the latest 'hype' that comes to mind. No more listening to the latest 'expert' on X tell me that "This is the absolute hottest thing in the 21st century..." Now, absolute focus rules. I've got little experience, so here on DEV, I'll be documenting my journey to a million dollars. I've got little I'll contribute to open source, build my projects, participate in hackathons and competitions... till I feel capable enough to go on my pilgrimage into the lands of the hackers. I won't be buying hype, I'll be building.  ( 6 min )

Artificial Intelligence (AI) is now increasingly making decisions that shape our online lives—from financial transaction approvals to health predictions and even decentralized network governance. As AI gets more robust, the need for trust, transparency, and accountability also grows. While bringing these in sync with privacy and data security is a daunting task. That is where Zero-Knowledge Proofs (ZKPs) step in. The AI Governance Challenge AI governance is not simply about governing algorithms—it is about ensuring decisions made by AI are: Fair: No hidden bias or prejudice. Transparent: Visible without having to indulge in blind trust. Private: Securing sensitive information while still being accountable. For example, imagine a decentralized AI system determining loan worthiness. Users …  ( 7 min )

Yesterday was supposed to be another regular day of coding and posting updates. Instead, my laptop decided to take an unscheduled vacation, leaving me with something I rarely experience: forced downtime. Having my laptop back means the usual stress is back too. And you know what? That's exactly what I need right now. I realized something during that forced break: without the productive pressure of work, my mind wanders to irrelevant stuff. Other people's drama, main character syndrome, overthinking random situations. The stress isn't my enemy - it's what keeps me focused on what actually matters. There's a difference between toxic stress and productive tension. The constant hum of having projects to work on, deadlines to meet, problems to solve - that's the kind of pressure that keeps me s…  ( 7 min )

72 hours of switching exposed the tradeoffs in speed, debugging, and deployment. 72 hours. One GPU. Too much coffee. I decided to run the same models back and forth between PyTorch and TensorFlow in 2025, just to see where each one actually holds up. Spoiler: both made me rage quit at least once. Why now? Because both frameworks leveled up big time: PyTorch 2.x introduced torch.compile(), which can turn your vanilla training loop into a speed demon. TensorFlow doubled down on production stability, with TF Serving still the gold standard for model deployment. And the surprise wildcard: Keras 3 now runs on TensorFlow, PyTorch, and even JAX meaning one codebase can literally swap backends like a gamer swapping GPUs. Some moments felt like a DX dream. Others felt like debugging spaghetti at …  ( 10 min )

In our previous article, we developed a basic AI agent that performed well enough when run from the console. However, this simple, linear approach has significant limitations in terms of speed and resource efficiency. Network connections to remote services and data retrieval from external servers are inherently time-consuming operations. This is due to the overhead of establishing a connection, transmitting data over the Internet, and closing the session — all before considering potential server load from other requests. What’s more, a critical component — such as the mailbox servers, the LLM model servers, or the outbound email servers — might be temporarily unavailable. By adopting an asynchronous approach for interacting with each external resource, we can dramatically accelerate the ov…  ( 14 min )

Welcome back! In our last post, I introduced myself and outlined the purpose of this series: to simplify React and guide you through the common pitfalls I faced. This article is our roadmap for Part 1: The Absolute Basics. This section will cover the essential building blocks of React, taking you from a complete beginner to someone who understands how to create and manage basic components. Here’s a look at what we'll be diving into: React Fundamentals & Your First Program. We’ll start with the very core of React and walk through writing your first program. Parent-Child Relationships. This is a crucial concept. We'll explore how components interact and share data with one another. The Evolution of React. We'll look at how React has evolved from class-based to function-based components and w…  ( 7 min )

The GPU shortage was just the tutorial. Now Europe’s real boss fight is the power grid here’s where devs can (and can’t) run workloads. Forget GPUs being rare. In Europe, the real loot drop is electricity. The big clouds and hyperscalers already maxed out Frankfurt, London, Amsterdam, Paris, and Dublin (aka FLAP-D), and now regulators and grid operators are literally the dungeon masters deciding who gets to deploy. If you missed it, Ireland and the Netherlands have basically said, “no more data centers until the grid chills,” while London’s grid is wheezing like your gaming laptop after 12 hours of Elden Ring. Europe’s AI boom isn’t just about who has the GPUs it’s about who can plug them in without tripping the entire region’s breaker. And yeah, it’s a bit like trying to run Stable Diffu…  ( 12 min )

Every profession has its own jargon. Football has “nutmegs,” marketing has “KPIs,” and developers… well, we have enough strange terms to make a newcomer think we’re summoning code spirits. Here’s my attempt at translating some of the words we use into real life. A feature’s evil twin. Shows up uninvited, often just before a deadline, and somehow multiplies when you try to squash it. Staring at your screen for three hours until you finally notice the missing semicolon that has been mocking you the whole time. The universe’s way of saying: “You thought something was there.

Nvidia’s GB200 NVL72 promises “exascale in a rack.” Here’s what that means for training, inference, and the cloud bills we cry over. So, Nvidia just casually dropped an exascale computer in a single rack. Yeah, you read that right. Exascale. One rack. If you’re thinking, “That sounds like a Minecraft server on steroids,” you’re not far off except this one costs more than your entire startup and its runway. The GB200 NVL72 is officially shipping this year thanks to HPE and QCT, and Nvidia is already bragging about it as “an exascale computer in a single rack.” Translation: the hardware arms race just leveled up, and everyone from hyperscalers to indie ML devs is either drooling or crying into their cloud bills.

Modern travel planning demands fresh, structured signals and predictable automation. Flight availability, hotel inventory, and local recommendations are time-sensitive and often encoded in vertical search outputs. AI agents can directly assist in solving this problem. A reliable AI travel agent will combine the reasoning capabilities of a language model with direct access to different search APIs. This post describes a follow-up to the research agent pattern (covered in prior AI agent blog): a travel planning agent that plans its retrievals, verifies structured inputs (IATA codes), runs targeted vertical searches (Flights, Hotels, Local/Maps, Web), and synthesizes concise, cited itineraries.

In this multi-part series, we'll explore how to build a modern, scalable pipeline for processing telecom Call Detail Records (CDRs) using Databricks Delta Live Tables. Part 1 focuses on the foundation: data generation and the bronze layer implementation. Telecommunications companies process billions of Call Detail Records (CDRs) daily. These records capture every interaction with the network—voice calls, text messages, data sessions, and more. Processing this data efficiently is critical for billing, network optimization, fraud detection, and customer experience management. In this series, we'll build a complete Telco CDR processing pipeline using Databricks Delta Live Tables (DLT). We'll follow the medallion architecture pattern, with bronze, silver, and gold layers that progressively ref…  ( 9 min )

Part 2 – Automating the Pipeline In Part 1 I wanted it to behave like a production-grade application: built, scanned, and deployed automatically with security woven into the process. This is the part where things got interesting — the pipeline. Let’s keep it real: my app is not a full-stack system. It’s a portfolio website — plain and simple. HTML for structure CSS for styling JavaScript for a little interactivity That’s it. But what made it special was how I treated it: I Dockerized it using an NGINX base image to serve static files. I pushed that image to AWS Elastic Container Registry (ECR). Then, I deployed it to Azure Container Apps using Terraform. Even though the app was static, the pipeline was dynamic.

Let’s imagine something for a second. You're minding your own business, managing AWS infrastructure for a client with a pretty standard e-commerce setup: a Medusa.js backend, a Next.js storefront, and most importantly for this story, a PostgreSQL RDS instance safely stashed away in a private subnet where nothing from the outside world can touch it. Exactly how the AWS gods intended. Then, one day, your client says: "Hey, I need to get access to the production database" Now, there are plenty of legit reasons to want this kind of access: analytics, dashboards, audits, maybe some light database spelunking.

🔹 Problem: 3021. Alice and Bob Playing Flower Game Difficulty: #Medium Tags: #Math, #Combinatorics Alice and Bob play a game with n flowers and m flowers. Each chooses one flower. Alice wins if the total number of petals is odd. You need to count the number of winning pairs (x, y) where 1 ≤ x ≤ n and 1 ≤ y ≤ m. Brute Force Idea: (x, y) and check if x + y is odd. That would be O(n * m), which is too slow for large inputs. Optimized Strategy: The solution was unexpectedly simple once I realized the parity logic: Alice wins only when one number is even and the other is odd. Count how many odds and evens are in 1..n and 1..m. odds_in_n = (n + 1) // 2 evens_in_n = n // 2 odds_in_m = (m + 1) // 2 evens_in_m = m // 2 Winning pairs = (odds_in_n * evens_in_m) + (evens_in_n * odds_in_m) Simplifies to (n * m) // 2. class Solution: def flowerGame(self, n: int, m: int) -> int: return (n * m) // 2 Time: O(1) Space: O(1) 🧩 Key Takeaways ✅ Learned how to reduce brute-force counting to simple parity logic. 💡 The trick is noticing that half of all pairs will have odd sums. 💭 In future, whenever I see problems about sums being odd/even, I’ll try counting odds and evens separately instead of brute force.

RAG (Retrieval-Augmented Generation) is one of the most practical ways developers are applying LLMs today. Large Language Models (LLMs) are very good at writing and reasoning in natural language. But used naively, they come with three practical limits: Hallucinations: LLMs can make things up because they predict text by pattern-matching. Outdated knowledge: LLMs knowledge is frozen at training time, so they don’t know new events after their last update. Limited context window: LLMs can’t fit huge knowledge bases, like company wiki or long PDFs, into their limited prompt window, so they miss crucial details. Retrieval-Augmented Generation (RAG) solves these problems by pairing an LLM with a search layer. Let's unpack that... Information Retrieval is finding relevant data within large…  ( 9 min )

Hey DEV community! 👋 Like many of you, I have a habit—some might call it an obsession—of keeping up with the latest technology. My evenings are often spent browsing GitHub Trending, watching "new tool" roundups on YouTube, and checking out what's new on Hugging Face. The thrill of discovery is great, but it always leads to the same bottleneck: a mountain of README files. The real challenge isn't finding new projects; it's evaluating them quickly. I constantly ask myself: How steep is the learning curve? Is it practical for a real-world project? How much of a headache will it be to deploy? These questions aren't answered by star counts alone. I needed deeper insights, but I didn't have the time to investigate every single interesting repo. So, winding down last Friday evening here in Indon…  ( 8 min )

Introduction Machine learning has quickly moved from research labs into our everyday lives. It powers things like voice assistants, fraud detection systems, personalized shopping recommendations, and even medical diagnoses. At its core, machine learning is about teaching computers to learn patterns from data and make predictions without being explicitly programmed for every task. What Is Classification? Examples include: Is this email spam or not spam? Is this transaction fraudulent or legit? Is this image a cat, a dog, or a bird? Process of classification: Collect Data – Gather labeled examples. Preprocess – Clean the dataset (remove duplicates, handle missing values, etc.). Feature Selection – Pick the most relevant features.

When working with data structures in Java, two of the most commonly used classes are ArrayList and LinkedList. Both are part of the java.util package and implement the List interface, which means they share many common methods. However, the way they work internally is different, and this difference makes each one suitable for different use cases. Based on Dynamic Array Fast Access (O(1)) Slow Insertion/Deletion Memory Usage Best Use Case searching and accessing elements is frequent. LinkedList Based on Doubly Linked Nodes Slow Access (O(n)) Fast Insertion/Deletion Memory Usage Best Use Case Side-by-Side Comparison Feature ArrayList (Dynamic Array) LinkedList (Doubly Linked List) Storage Dynamic Array Doubly Linked Nodes Access (Read) Fast – O(1) Slow – O(n) Insertion/Deletion Slow (shifting needed) Fast (update node links) Memory Less (stores only data) More (data + next + previous references) Best For Searching & frequent access Frequent insertions & deletions Apart from the common List methods, LinkedList provides some additional methods: addFirst() – Add element at the beginning addLast() – Add element at the end getFirst() – Retrieve first element getLast() – Retrieve last element removeFirst() – Remove first element removeLast() – Remove last element  ( 6 min )

When deploying applications in Google Cloud Platform (GCP), managing virtual machines (VMs) individually can become complex and inefficient. That’s where Instance Groups come into play.

Docker has become a must-have tool for modern software development. Whether you’re building web apps, APIs, or microservices, Docker makes it easier to package, ship, and run applications in a consistent way. If you’re new to Docker, here’s a simple beginner-friendly guide to get you started. Docker is a platform that lets you run applications inside containers. Consistency → Works the same on your machine, staging, and production. Portability → Run anywhere (Linux, Windows, macOS, cloud). Isolation → No more "it works on my machine" issues. Efficiency → Faster and lighter than full virtual machines. Image → A snapshot/template of your app. Container → A running instance of an image. Dockerfile → Instructions for building an image. Docker Hub → A public registry for Docker images. # Check Docker version docker --version # Run a container docker run hello-world # List running containers docker ps # Stop a container docker stop # Remove a container docker rm docker run -d -p 8080:80 nginx ➡️ Visit http://localhost:8080 and you’ll see the Nginx welcome page. # Use Node.js base image FROM node:16 # Set working directory WORKDIR /app # Copy project files COPY . . # Install dependencies RUN npm install # Start the app CMD ["npm", "start"] Then build and run: docker build -t my-app . docker run -p 3000:3000 my-app Docker helps developers build and deploy apps faster, with fewer headaches.

When you use a CDN, cached copies of your website’s static assets are stored at the network edge for fast delivery to your visitors. Well, if your website is just those assets, why not just dump the whole thing at the edge and serve it directly from there instead of storing it on a web hosting service in the first place? That's what the JavaScript Static Publisher for Fastly Compute does. It delivers your static site straight from the network edge using a serverless app to handle user requests, and an edge data store for your content. This kind of originless setup is well suited to generated static sites made up of HTML, CSS, and client side JavaScript, like blogs and react apps.

Given an array of integers nums and an integer target, return indices of the two numbers such that they add up to target. You may assume that each input would have exactly one solution. You cannot use the same element twice. You can return the answer in any order.

One of the most common challenges for automation engineers using JavaScript/TypeScript is handling asynchronous code. Whether you’re writing tests in Playwright or Cypress, you’ll often deal with actions that don’t resolve instantly — such as page navigation, element interactions, or API calls. That’s where Promises, async, and await come in. Let’s break them down with automation-specific examples. What is a Promise? A Promise represents the eventual completion (or failure) of an asynchronous operation. Think of it like a “contract” — “I’ll give you the data when it’s ready.” Example: Fetching Data const dataPromise = fetch('https://api.github.com/users'); dataPromise.then(response => response.json()) .then(data => console.log(data)); In test automation, every browser action i…  ( 7 min )

For over two decades, Robert C. Martin’s S.O.L.I.D. principles have served as the North Star for every serious developer. We study them, we discuss them in interviews, and we strive to apply them in our code. But there’s a problem. S.O.L.I.D. is a “gentleman’s agreement.” It’s a philosophy that lives in the minds of architects and on the pages of books, but remains almost invisible in the code itself. How can you prove that your code truly adheres to the Single Responsibility Principle? How can you ensure a new team member won’t violate the Dependency Inversion Principle? Until now, the answer has always been: “Trust in code reviews and the experience of your team.” That answer is now obsolete.

Over five weeks, I went from theory to practice, building two data-driven web applications that brought my B.Tech. studies in Artificial Intelligence and Machine Learning to life. My goal was to apply my Python skills to real-world problems, with a focus on API integration, data processing, and backend development. The entire experience was a crash course in the software development lifecycle, from designing the architecture to writing code and managing it with Git. This was my first major project, a web-based application to track live stock price…  ( 7 min )

My journey took an exciting turn when I discovered several tools that significantly accelerated my development process. I adopted what I call "vibe coding" - a development philosophy that prioritizes maintaining momentum and a positive mindset while coding. Rather than getting stuck in analysis paralysis, I focused on writing code that felt right and solved problems efficiently, even if it wasn't perfect. This approach helped me stay motivated and make consistent progress, especially during challenging phases of development. One of the game-changers in my development journey was using Cursor, an AI-powered code editor. With Cursor: I could describe functionality in plain English and get code suggestions Debugging became more intuitive with AI-assisted error analysis I learned new programmi…  ( 7 min )

You know the feeling. Your customer support queue is exploding, your CSAT scores are plummeting, and your old rule-based chatbot is about as useful as a screen door on a submarine. It can parrot pre-written answers, but the moment a customer has a complex, multi-step problem—it fails. Spectacularly. This was the exact reality for "GlobalEcom" (a fictional name for a very real problem we solved). Their growth had outpaced their support infrastructure. They didn't need a better chatbot; they needed an intelligent AI agent that could reason, take action, and learn. And it needed to be built to scale. This is the story of how we architected that solution on AWS, creating a system that not only handled a 300% surge in queries but did so while reducing costs and improving resolution rates. Globa…  ( 8 min )

Vaadin has always been a bit different. Yes, it's a Java framework. Yes, it’s great for building modern web UIs. But if you’ve ever used Vaadin seriously, you’ve probably noticed something that sets it apart: its component architecture. Whether you're using a ready-made component from the official library, building your own from scratch, or integrating a 3rd-party NPM package, all Vaadin components follow a consistent maintainable structure that bridges the server and the client and can evolve along with your application. There are lots of UI libraries out there. React has its components. Lit has web components. Bootstrap has... buttons. Vaadin? It’s not just about visuals. It is not uncommon that Vaadin application and components are developed and maintained for many years. That is by d…  ( 8 min )

Light and dark themes have been around for a while, but there is still no way to configure them in PWAs. Or rather, there is no standard at the manifest level: I found a solution to overcome this limitation. It follows the conventions, even though we aren’t going to use the manifest. Unfortunately, manifests are static JSON-formatted files which can’t change on user input. This means that they can only provide a theme_color key at a time: there’s no chance to make it dynamic. So, what if you want to support both light and dark themes? You have to choose between the two. Ish. You can use a combination of CSS and JavaScript to let users set their own preferred theme, but you can’t change the theme_color accordingly—not from the manifest, at least. All is not lost! You can always choose not t…  ( 7 min )

We are living in the golden age of AI assistants. They write code, find bugs, and refactor entire modules. But they have a fatal flaw that turns any complex project into a swamp. That flaw is contextual amnesia. Human ↔ Human Communication The Problem: A new developer spends weeks just to get up to speed. Key project knowledge is stored in the minds of veterans and is lost when they leave. The Solution with AOKL: A developer opens any file and, within 30 seconds, gets answers to the most important questions: What is this file for? What is its place in the architecture? What is it connected to? AOKL becomes the universal, always-current source of truth. Human ↔ AI Communication The Problem: The infamous "contextual amnesia." Endless iterations in prompts. The Solution with AOKL: Instead of asking, "fix this bug, but remember that this module works with Stripe payments...", you simply provide the code with an AOKL block: code Aokl /** @PURPOSE: Processing transactions via the Stripe API. @INTEGRATION: User_Profile_API, Billing_DB. */ For the AI, this is no longer a request. It's a comprehensive technical spec. AI ↔ AI Communication The Problem: Today’s AI agents are incapable of collaborating effectively. The Solution with AOKL: AOKL becomes the lingua franca that allows a swarm of AI agents (Architect, Coder, Refactorer, Tester) to work together seamlessly on a single project. Conclusion We stand at the dawn of a new era, where a developer's value is defined by their ability to clearly articulate architectural intent. AOKL is the tool for this new era. It transforms an AI assistant from a "helper" into a true "partner" and lays the foundation for future autonomous development systems.  ( 7 min )

When building an API in Go, you may notice you keep writing this kind of code everywhere: if email == "" { validationError := responses.Response{ Code: 422, Message: "Invalid email", } w.WriteHeader(http.StatusUnprocessableEntity) json.NewEncoder(w).Encode(validationError) return } This gets repetitive, messy, and hard to manage as your project grows. If you're coming from Laravel, you're used to something like throw new Exception(...), and having Laravel automatically return a proper JSON response. In Go, you can achieve the same thing using: A custom error type Middleware panic() + recover() Let’s build it together 👇 Stop repeating the same error-handling code Throw errors in one line Always return a clean JSON response Centralize the logic in …  ( 7 min )

“In today’s world, your code might get you noticed… but your brand will get you remembered.” Not too long ago, I met a brilliant developer—we’ll call him Tunde. His GitHub was full of innovative projects: clean code, unique solutions, and well-documented repositories. Yet, he often complained, “No one seems to notice what I build.” The problem wasn’t his skill. It was visibility. A few months later, Tunde started doing something different: He shared short tutorials on LinkedIn. He posted Twitter/X threads about debugging lessons. He wrote a blog post explaining how he optimized an API. The result? Recruiters reached out, other devs engaged with his content, and he even got invited to speak at a local tech meetup. 👉 The lesson? Personal branding is no longer optional for developers—it’s a …  ( 7 min )

We, the architects of digital worlds, are drowning. We are drowning in “swamp” of low throughput — not between servers, but between intellectual entities: human and AI, and even human and human. I, Vladimir Igorevich Evpolov, drowned in this swamp while working on one of the most complex B2B projects of my 18-year career. My AI partner suffered from “contextual amnesia.”. Each new request was like a new day. And I turned from an architect into a nanny for a genius. Efficiency tended to zero, slowing down the entire process AI development. Press enter or click to view image in full size The problem goes deeper. How many hours were wasted because a new developer on the team didn’t understand the “unwritten” intentions of the old one? Our most valuable asset, the architectural concept, is lost with every transmission. We communicate at the speed of speech, while machines communicate at the speed of light. It was to solve this problem that the protocol was created. Architecture-oriented commenting (AOC). What is Architecture Oriented Commenting (AOC)? Basic Principles of the AOC: @file: File name. The world is looking to Elon Musk’s neural implants as a solution. It’s a “brute force” approach: an attempt to directly connect our biological brains to a machine. But it’s risky, expensive, and, for most, scary. I believe the answer lies not in risky surgery, but in elegant engineeringWe shouldn’t change the person. We should improve the language we communicate through code. AOK is our first step towards creating a future where AI development will not be slow and painful, but fast, effective and limitless. I invite you to join this revolution.

In software development, how we structure applications significantly impacts scalability, maintainability, and deployment. Traditionally, applications followed a monolithic architecture, but as systems grow complex, microservices offer a more flexible alternative. Let’s explore the basics. What is a Monolithic Architecture? In a monolithic architecture, all features—like authentication, payments, orders, and shipping—are bundled into one large codebase. This works for small applications but poses challenges for larger systems: Single Point of Failure: If one module (e.g., inventory) fails, the entire app can crash. Scaling Issues: Scaling one feature means scaling the whole system, which is inefficient. Risky Deployments: A single bad update can break the entire application. For exa…  ( 6 min )

When working with Angular, you’ve probably noticed that your development server often runs on localhost:4200. But what does this really mean, and why is it important for your development workflow? In simple terms, localhost refers to your own computer, typically mapped to the IP address 127.0.0.1. The number 4200 is the default port chosen by the Angular team for the development server. When you see http://localhost:4200/ in your browser, it means an Angular application is running locally in development mode. This setup allows you to see live changes in your application as you work, thanks to features like live reload and hot module replacement. The choice of port 4200 wasn’t random, it was selected to minimize conflicts with other common ports used by development tools. When you run comma…  ( 7 min )

If you’ve ever configured a Wi-Fi router or set up a server, you’ve probably stumbled across something like 255.255.255.0. That strange number is a subnet mask — and it plays a crucial role in how devices know whether they should talk directly to each other or send data through a router. Let’s break it down in simple terms. Every device on a network has an IP address, and that address has two parts: Network part → Identifies which network the device belongs to Host part → Identifies the specific device inside that network Example: 192.168.1.42 192.168.1 = Network part 42 = Host part But how do we know where the split happens? That’s where the subnet mask comes in. A subnet mask tells a device which portion of the IP address is for the network and which portion is for the ho…  ( 7 min )

If you’ve been tracking PC hardware prices lately, you may have noticed something puzzling: the price of DDR4 RAM is rising — even though it’s no longer the latest memory standard on the market. With DDR5 now more widely available, logic would suggest that older DDR4 modules should become cheaper. So why is the opposite happening? This article explores the key reasons behind the increasing prices of DDR4 RAM and offers insights into the market forces and industry decisions driving this trend. Whether you’re a PC builder, gamer, system integrator, or simply curious about tech economics, this blog will give you a clear and in-depth understanding of the situation. The most fundamental reason behind rising DDR4 prices is the industry-wide shift to DDR5. As more consumers and businesses adopt n…  ( 8 min )

In the era of remote work, hybrid infrastructure and cloud solutions, a reliable and secure connection to corporate resources is not just a wish, but a mandatory requirement. Especially when it comes to accessing data and services located in a data center. Today we will figure out which methods of secure connection to a data center are relevant in 2025, and how technologies such as IPSec VPN, WireGuard, SSL VPN and others differ from each other. 📡 Why do you need a secure channel at all?

Especially if employees, partners or services connect from outside, via the Internet. An encrypted tunnel provides: Confidentiality (data is not read in transit) Integrity (i…  ( 7 min )

Routers and Route Tables: The GPS of the Internet When you send an email, stream a video, or open a website, your data doesn’t travel in a straight line. Instead, it jumps from network to network, guided by one of the most important devices on the internet: the router. Routers are like the GPS of the digital world, ensuring every packet of data finds its way across the vast highways of the internet. And the secret to their intelligence lies in something called the route table. A router sits at Layer 3 of the OSI Model — the Network Layer. Its job: move data between different networks. While a switch connects devices inside a local network (LAN), a router is the bridge that connects one LAN to another — and eventually to the internet. Every router has one or more network interfaces …  ( 7 min )

If you’ve ever felt like the SOLID principles sound too abstract, don’t worry; in this article we’ll break them down into simple, relatable examples with analogies. By the end, you’ll understand each one in a way you’ll never forget. Let’s dive in! 1. Single Responsibility Principle (SRP) Each app does one job well. If your camera app also tried to send messages and play music, it would become messy and hard to maintain. In code terms, this means: ❌ Don’t do this: ✅ Do this: Each class does one thing well, making it easier to maintain, test, and reuse. 2. Open/Closed Principle (OCP) This means classes should be open for extension but closed for modification. In the sense that you should be able to add new features without changing existing code.

To build great products, start by listening. Everything matters. Every bug report, feature request, or glowing review. These are the signals that fuel your product roadmap. However, standing between success and failure is the pain of managing and routing that feedback to the right teams. According to a Zendesk report, 59% of support teams are overwhelmed. Feedback pours in from multiple channels, often causing delays and leaving users feeling ignored. Support teams want to help; they try to, but the fragmented channels jeopardize their efforts.

When you first install WordPress, everything feels simple: a fresh site, a dashboard that looks clean, and endless possibilities. But it doesn’t take long before small mistakes pile up and make the site harder to maintain, slower to load, or even insecure. After more than a decade working as a freelance WordPress developer, these are the basic mistakes I see over and over again — and how to avoid them. The WordPress ecosystem is full of plugins. Many of them are useful, but too many create problems. Every plugin adds extra code, extra database queries, and a higher chance of conflicts. A better habit is to keep a core stack of trusted plugins and learn them deeply instead of installing new ones for every task. For example, I work mainly with Elementor Pro, JetEngine, WP Rocket and Fl…  ( 7 min )

In modern software delivery, containerization has become the de-facto standard for packaging and deploying applications. While Docker Hub is widely used, many organizations rely on private registries (Harbor, Nexus, Artifactory, AWS ECR, Azure ACR, Google GCR, etc.) to securely host and distribute container images. This blog walks you step-by-step through the process of creating a project locally, building a Docker image, and pushing it directly to a private Docker repository. Before you begin, ensure you have: Docker installed on your local machine. Access to a private registry (credentials + URL). A project to containerize (we’ll use a Java Spring Boot example here). Let’s assume you have a Spring Boot application. Build it locally: mvn clean package -DskipTests This will generate an ex…  ( 7 min )

Introduction Automating user interfaces has come a long way—but there are still situations where traditional methods fall flat. One of the biggest challenges arises when working with canvas-based applications, where no DOM elements exist for key interactive components. This makes it nearly impossible for standard test frameworks to simulate interactions like clicks, taps, or hovers using selectors alone. This blog post introduces a novel solution to this problem: the wdio-visual-click-service, a new plugin for WebdriverIO that allows test scripts to interact with UI components using image matching instead of DOM queries. In modern UI automation, developers and software engineers in test often run into limitations when trying to interact with components that don’t expose reliable DOM sele…  ( 10 min )

"Back to school" is here... (at least in France), but have you ever tried to fit a whole school into an Excel file? 🤔😄 While the question seems strange, this is exactly what an ORM (Object-Relational Mapping) aims to do. Imagine you're a principal and you have to enter all the students, their parents, teachers, subjects, classes, etc., and most importantly, all the relationships that link them, into your spreadsheet. It's quite a puzzle! If we were to create an application to help our principal, the ORM would be there to help us distribute these concepts (student, parent, teachers...) into the sheets of the Excel file (more specifically, into the tables of the database). It would then allow us to access them to find out if H.Potter has a Math class on Tuesday from 2 p.m. to 3 p.m., or to…  ( 6 min )

I am kind of ranting here so Je suis désolé... This year was kind of rough on me, both the year and me. I graduated in May 15 of this year. Commuting to college, going to the gym , meal prep, taking care of sick grandma , assignments , exam preps, getting 20 k steps a day consumed all of my attention and time. Plus my social media doom scrolling didn't help. As a wise man once said "The chains of habit are too light to be felt until they are too heavy to be broken" . I am the living example of that. It is very easy to let go of discipline, routine that makes someone great. When chaos or entropy eventually gets in the way of your idealized version of life, do you persevere or quit, and that is the deciding factor. Moving on I think it's my responsibility to rise above the hurt and chaos. I owe it to my future self, I am worth it. If you read this I am very grateful.  ( 6 min )

AI startups are everywhere right now. New tools, new APIs, new venture rounds. But if you zoom out, the survival rate isn’t very encouraging. Most AI startups fail within a few years, not because of lack of hype, but because they couldn’t translate cool demos into sustainable businesses. Here are a few notable cases, what went wrong, and the takeaways for developers and builders. MetaMind wanted to bring deep learning as an easy service for businesses. Backed by big names like Marc Andreessen, it was later acquired by Salesforce and folded into Einstein AI. Problem: Tech differentiation was weak. Google, Microsoft, and AWS offered stronger models as APIs, often at low or no cost. Competing with hyperscalers in “generic AI services” is almost impossible.

Imagine this: What happened? Cold Starts in serverless computing. They’re invisible to most developers until they strike—and when they do, performance takes a hit. In serverless architectures (like AWS Lambda, Azure Functions, Google Cloud Functions), your code doesn’t run continuously. Instead: The provider spins up a new container to run your function. This initialization process adds extra latency. That delay = a “Cold Start.” If your function has been inactive for a while, the next request will likely hit a cold start. Cold starts might sound harmless, but they can silently kill user experience: ❌ Higher response times for the first request. ❌ Poor experience in latency-sensitive apps (chat, payments, APIs). ❌ Frustrated users → higher bounce rates. Real talk: Even a 1-second delay ca…  ( 7 min )

API ইন্টিগ্রেশন করতে গিয়ে কি কখনো মনে হয়েছে, "ধুর, এর চেয়ে তো ম্যানুয়াল কাজ করাও ভালো ছিল!"? আমরা যখন নতুন কোনো সার্ভিস বা পেমেন্ট গেটওয়ে ইন্টিগ্রেট করি, তখন সবচেয়ে বড় চ্যালেঞ্জ হয় documentation। অসম্পূর্ণ বা confusing documentation, inconsistent response format, আর হঠাৎ করে আসা error—সব মিলিয়ে মাথা খারাপ হওয়ার জোগাড়। আমি এই চ্যালেঞ্জগুলো তিনটি ধাপে মোকাবিলা করি: ১. প্রথমে ডকুমেন্টেশন পড়া: কোনো কোড লেখার আগে API-এর ডকুমেন্টেশনটা ভালো করে পড়ে নেই। কোন endpoint কী কাজ করে, কোন parameters পাঠাতে হবে, আর response কেমন আসবে—এগুলো ভালোভাবে বোঝার চেষ্টা করি। ২. Postman দিয়ে টেস্টিং: সরাসরি কোডে হাত না দিয়ে প্রথমে Postman-এর মতো টুল ব্যবহার করে প্রতিটি endpoint টেস্ট করে নেই। এতে করে authentication, request format আর error handling-এর ব্যাপারটা পরিষ্কার হয়ে যায়। ৩. সুন্দর Error Handling: এরপর যখন কোডে API কল করি, তখন শুধু happy path নিয়ে ভাবি না, একই সাথে error handling-এর জন্য একটি robust mechanism তৈরি করি। যেমন, যদি কোনো কারণে API downtime-এ থাকে বা unexpected response পাঠায়, তখন যেন অ্যাপ্লিকেশন ক্র্যাশ না করে, বরং ইউজারকে একটি সুন্দর মেসেজ দেখাতে পারে। আপনার সবচেয়ে চ্যালেঞ্জিং API ইন্টিগ্রেশনের অভিজ্ঞতা কোনটা ছিল? কোন API আপনাকে সবচেয়ে বেশি ভুগিয়েছে? কমেন্টে আপনার অভিজ্ঞতা শেয়ার করুন!  ( 6 min )

The CAP theorem, introduced by Eric Brewer in 2000, helps us understand the limitations of distributed systems. It says: 👉 In a distributed system, you can only choose 2 out of 3 properties at the same time: Consistency (C) Availability (A) Partition Tolerance (P) You cannot have all three at once. Meaning: Every read gets the latest written data (or an error if not possible). Analogy: Imagine you update your WhatsApp profile picture. If your friend checks it, they should see the latest photo immediately. Real-World Example: In banking systems, if you transfer $100 from your account, the system must instantly update the balance everywhere. Otherwise, you could withdraw money twice. Here, Consistency is critical. Meaning: The system always responds to requests (read/write), ev…  ( 10 min )

Everyone's talking about Google's Guardrailed-AMIE, but the real shift isn't the AI—it's how doctors and machines team up for safer, faster care. Most AI in healthcare promises speed and misses trust. Patients and clinicians need both. The winners will design for safety, workflow, and proof. Google's Guardrailed-AMIE points to a better pattern. Multi-agent AI interviews patients, drafts a structured note, and flags uncertainty. Then a physician reviews, edits, and approves before anything goes back to you. That sequence builds accountability, auditability, and real adoption. When humans stay in the loop, risk drops and ROI goes up. Picture a mid-size clinic testing this for intake and triage. In month one, average intake time drops from 12 minutes to 8. Clinicians recover 10 hours a week, and patient wait times shrink 18%. Every answer includes sources and a clear record of who approved it. ↓ The Human-Guarded AI Playbook. • Start with one high-friction flow: intake, FAQs, or refills. • Map risks and escalation paths, then set physician gate checks. • Capture structured data, sources, and edits for an audit trail. • Ship patient-facing language at an 8th grade reading level. ↳ Launch in 90 days: pilot one team, measure time saved, expand stepwise. ⚡ Faster visits, fewer errors, higher trust. ⚡ Leaders get scale without burning out clinicians.

1️⃣ Introduction Agent-to-Agent (A2A) Protocol is an open standard that enables independent AI agents to discover each other, share capabilities, and collaborate on tasks in a secure and interoperable way. Instead of building one monolithic agent, A2A allows specialized agents—such as a planner, researcher, or executor—to communicate seamlessly across different frameworks and organizations. By defining a common structure for discovery (Agent Cards), task management (Task lifecycle), and communication (messages & parts), A2A provides the foundation for scalable, multi-agent ecosystems where agents can work together much like microservices do in modern software architectures.

When deploying compute workloads in Google Cloud, you generally choose between Persistent Disks (PDs) and Local SSDs. Persistent Disks: Durable, network-attached, can be resized, backed up with snapshots, and survive VM reboots.

Histogram in R How to create histograms in R To start off with analysis on any data set, we plot histograms. Knowing the data set involves details about the distribution of the data and histogram is the most obvious way to understand it. Besides being a visual representation in an intuitive manner. It gives an overview of how the values are spread. We come across many depictions of data using histograms in our day to day life. For example, the distribution of marks in a class can be best represented using a histogram and so does the age distribution in an organization. The good thing about histograms is that it can visualize a large amount of data in a single figure and convey lots of information. It is quite easy to spot the median and mode by looking at histograms. A histogr…  ( 12 min )

If you’ve played with AI image tools, you probably know the frustration: sometimes you type something simple and the result looks nothing like what you imagined 😅. That’s where** ***prompt engineering* comes in. It sounds fancy, but honestly, it’s just learning how to give AI the right instructions so you get better results. Think of AI like a waiter at a restaurant 🍽️. If you just say,** “I want food,” you might get something random. But if you say, **“I’d like a cheeseburger with extra cheese, no onions, and crispy fries on the side,” you’re way more likely to get exactly what you want. Prompt engineering works the same way — the clearer your prompt, the better the image. Be Clear, Be Specific ❌ “Dog in park” Mention Style or Vibe Want it to look like a painting, 3D art, or a cartoon? Just say it. Play with Mood & Lighting Lighting changes everything! Add Camera or Art References 👉 “Landscape of snowy mountains, wide-angle lens, sunrise, National Geographic style” Experiment, Don’t Stop at One Your first prompt won’t always be perfect. Tweak words, change the order, and see what happens. AI responds well to trial and error. Here’s a simple formula I use for almost every prompt: [Subject] + [Action] + [Details] + [Style/Lighting/Camera] 👉 Example: Saves you time (no endless re-generating) Makes your images look more professional Gives you more creative control instead of leaving it all to chance Prompt engineering isn’t some “expert-only” skill. It’s just practice. The more you play around with your prompts, the more natural it feels — and the better your AI images get. So next time, don’t just type** **“dog in park.” Add a little extra detail, throw in a style, mention the vibe you’re going for, and watch the magic happen ✨. At the end of the day, it’s not about the AI. It’s about how** **you talk to it. 🔥 If this helped, share it with a friend who’s also messing around with AI art. Trust me, they’ll thank you later!  ( 7 min )

When you interact with Large Language Models (LLMs) like GPT-5, LLaMA, or Claude, it feels like you’re sending sentences and paragraphs. But under the hood, the model doesn’t “see” text the way we do. Instead, everything you type is broken down into tokens—tiny units that sit at the heart of how LLMs process, generate, and price their outputs. In this post, we’ll dive deep into tokenization in machine learning, why it matters for developers, and how you can actually experiment with tokenizers using tools like tiktokenizer. Tokenization is the process of splitting text into smaller units called tokens, which are then mapped to numerical IDs and embedded into vectors for processing.

Uma nova Era na Programação: A Historia do Kotlin A Introdução á Linguagem que Mudou o Jogo Em 2011, a equipe da Jetbrains, uma renomada empresa de software, tinha um grande objetivo: criar uma linguagem de programação para a Máquina Virtual Java (JVM) que fosse mais pragmática, segura e concisa. Eles sabiam que, para desenvolver aplicações de forma mais eficiente, precisavam de uma ferramenta que otimizasse o trabalho, sem sacrificar a robustez e a compatibilidade. A ideia era construir uma linguagem que fosse completamente interoperável com o Java, permitindo que os desenvolvedores pudessem utilizar o melhor de ambas no mesmo projeto. O Nascimento do Kotlin A linguagem foi batizada de Kotlin, uma homenagem a uma ilha russa, próxima á sede da JetBrains. O nome, além de ser uma pequena e c…  ( 9 min )

Di Ceph ada beberapa service utama: MON, MDS, dan MGR (selain OSD). Fungsi: Menyimpan cluster map, informasi topologi cluster: OSD, PG, pool, crushmap, quorum. Menyediakan quorum → cluster Ceph butuh mayoritas MON hidup supaya bisa ambil keputusan. Jadi semacam “otak koordinasi”: siapa OSD yang up/down, siapa MDS aktif, dll. Tanpa MON: Best Practice: Minimal 3 MON untuk quorum (HA). Dengan 3 node cluster → biasanya setiap node dipasang 1 MON. Metadata Server (MDS) Fungsi: Khusus untuk CephFS (Ceph Filesystem). Mengelola metadata file (struktur direktori, permission, nama file, inode). Membuat akses file di CephFS jadi cepat, karena OSD hanya menyimpan data mentah. Tanpa MDS: Ceph RBD (block storage) tetap jalan. CephFS tidak bisa diakses (nggak bisa mount). Best Practice: Minimal 1 active MDS + standby MDS untuk failover. Kalau banyak client CephFS, bisa jalankan beberapa MDS active (multi-MDS) biar scalable. Fungsi: Tanpa MGR: Cluster masih jalan (MON + OSD masih cukup), tapi: Tidak ada dashboard Tidak ada modul tambahan (prometheus, radosgw, balancer). Best Practice: MON → otaknya Ceph → cluster map, quorum, konsensus. MDS → khusus CephFS → urus metadata file/direktori. MGR → pengawas + dashboard → monitoring & modul integrasi. OSD → Untuk menyimpan data & replikasi.  ( 6 min )

Introduction Polymorphism is one of the hardest concepts for new programmers to understand. The word itself looks complex and can confuse beginners. Many learners struggle because the explanations they find are filled with theory and technical terms. This makes the topic feel harder than it is. The aim of this document is to explain polymorphism in simple terms. You will see how it works through clear examples from everyday life. The goal is to help you understand what polymorphism means and how you can apply it in JavaScript. Real life comparisons, like a house lamp, phone charger, vehicles, and remote control, will make the concept practical and easy to remember. Polymorphism means one name with many forms. A single method or function behaves differently depending on the object or cont…  ( 8 min )

Aunque parece sencillo conectar vía SSH con este magnífico laboratorio de sabiduría, no es fácil. Tras mucha pelea he conseguido la manera de conectarme y al mismo tiempo crear un alias en mi terminal de linux para acceder de forma más rápida a ese host. Metasploitable2 usa un servidor SSH muy viejo, que solo ofrece algoritmos obsoletos (ssh-rsa con SHA-1 y ssh-dss). Las versiones modernas de OpenSSH (las que tienes en Kali, Ubuntu, Parrot, etc.) los deshabilitan por defecto, por eso falla. sí intentamos un: ssh msfadmin@192.168.1.155 nos tira el siguiente error Unable to negotiate with 192.168.1.155 port 22: no matching host key type found. Their offer: ssh-rsa,ssh-dss Con el siguiente comando forzamos a tu cliente SSH a aceptar claves débiles antiguas (ssh-rsa) que el servidor Metasploitable2 todavía usa, para que la conexión no falle por “no matching host key type”. ssh -oHostKeyAlgorithms=+ssh-rsa -oPubkeyAcceptedKeyTypes=+ssh-rsa msfadmin@192.168.1.155 En pocas palabras, le decimos lo siguiente: Oye SSH, ignora las restricciones modernas y conéctate a este servidor antiguo usando claves ssh-rsa. Ahora viene la segunda parte del ejercicio crear un alias en nuestro archivo de configuración de ssh. Para que las próximas veces solo tengamos que poner la contraseña para conectarnos a metasploitable. creamos el archivo de configuración de ssh en la siguiente ruta si no existiera sudo nano ~/.ssh/config Si no estamos como Super usuario o sudo le damos la contraseña y dentro del archivo pegamos lo siguiente: Host metasploitable HostName 192.168.1.155 # IP actual de la VM User msfadmin HostKeyAlgorithms +ssh-rsa PubkeyAcceptedAlgorithms +ssh-rsa con esto conseguimos evitarnos volver a escribir todos los comandos anteriores y con un simple... ssh metasploitable entraremos vía ssh a tan magnifico laboratorio a trastear.  ( 6 min )

Mobile apps are everywhere. Whether it's a banking app, a fitness tracker, or a marketplace for local goods, almost every business building digital products today has a mobile application at its core. But while app development has accelerated, security often struggles to keep up. Mobile application testing is a critical part of a secure software development lifecycle. Unfortunately, many development teams still underestimate the risks, or assume that app stores, operating systems, or third-party libraries will take care of it all. They don't. There are two sides to mobile application security testing: the application itself, and the API it talks to. Both need proper penetration testing. Most mobile apps run on iOS or Android, and a lot of teams rely heavily on the security of those platfo…  ( 8 min )

Crypto analysts told Cointelegraph investment advisers increasing their Ether and Bitcoin exposure signals a shift to portfolio-driven allocations, with more room to grow.

Fenwick & West, a law firm once contracted by FTX, has asked a judge to toss a proposed lawsuit that claims it was key to the exchange’s fraud.

Bitcoin traders have been buying all the dips but BTC is still stuck in a downtrend. Here’s why.

Finding, exploiting, and extracting database information through SQL Injection (SQLi) vulnerabilities in the search and login features is the goal. I successfully conducted a security assessment on the purposefully weak website testphp.vulnweb.com, which is documented in this article. Finding vulnerabilities in SQL Injection, a serious web application security vulnerability, was the main goal of the evaluation. To validate my suspicions, I started with manual testing before using automated tools to further attack the system. The following were the main findings: Vulnerability Verified: It was discovered that the artists.php page's artist parameter was extremely vulnerable to SQL injection. Automated Exploitation Obstacles: Connection resets initially prevented direct automation with sql…  ( 9 min )

Client I am making a website for a mobile detailing business. I start with a simple roadmap when making a website for a client. First, I talk with the client about what they want. Then, I make a list of questions about their business. This is to create the content for the website, and I place it in my notes or in Google Docs. I then interview the business owner and write down the answers to all my questions. This interview allows me to form the paragraphs for the different sections and pages. I learned from The Website Architect to only begin forming the layout and design after getting the content. This allows you to make the design custom-fit to the content. I make a mood board on Figma to gather inspiration for the website. I find websites everywhere I can, like from Awwwards. My wire…  ( 7 min )

In the study of Go language, the expansion strategy of arrays and Maps is a common and classic topic. This article aims to summarize and explain the expansion strategies of arrays and Maps. In Go, dynamic arrays are called slices. A slice provides a flexible and dynamically sized array solution. When using the append function to add elements to a slice, Go decides whether to expand the capacity based on the current capacity of the slice. The strategy for slice expansion in Go is as follows: First, if the newly requested capacity is greater than twice the old capacity, the final capacity will be the newly requested capacity; Otherwise, if the length of the old slice is less than 1024, the final capacity will be twice the old capacity; Otherwise, if the length of the old slice is greater tha…  ( 9 min )

🔍Semantic HTML Importance for SEO and Accessibility*🔎 **👋Introduction ✨When I first started learning HTML, I used a lot of that looked like a header, but a search engine or screen reader would just see "a div". That’s when I learned about semantic HTML. Semantic HTML uses tags that describe their purpose, like , ,, , and . These tags don’t just make code cleaner – they also improve SEO (Search Engine Optimization)🕵️‍♀️ and accessibility👩‍🦽. In this article, I’ll explain ✨what semantic HTML is, ✨why it matters, ✨how to implement it, and I’ll share ✨examples you can try in your own projects. Semantic HTML means using tags that carry meaning. Instead of only using generic tags like , we use tags that explain the role of t…  ( 8 min )

A few years ago, if you didn’t speak English and had no money to buy learning resources, your options for studying technology were very limited. The quality and variety of programming material were scarce, and without someone to guide you, following the path was tough. Today, with the explosion of information in every language —and even with AI— learning is still a challenge. For beginners without a mentor, it is hard to decide where to start. Choosing which technologies to learn and focus on can have a big impact on your economic future. However, if you are just starting, you can pick from the TOP 10 languages or technologies and go with the one you like the most. The dangers that can take you off track Once you start learning one technology, new opportunities, projects, or job offers …  ( 7 min )

Protecting user data in Flutter apps is critical to building trust and ensuring compliance. This blog explores key practices to secure your Flutter app, from data storage to network communication, helping you create robust and reliable applications. Storing sensitive data like passwords or API keys securely is essential to prevent unauthorized access. Use flutter_secure_storage: Leverage platform-specific secure storage (e.g., Keychain on iOS, Keystore on Android) for sensitive data. Example: import 'package:flutter_secure_storage/flutter_secure_storage.dart'; final storage = FlutterSecureStorage(); // Write data await storage.write(key: 'auth_token', value: 'your_token'); // Read data String? token = await storage.read(key: 'auth_token'); Avoid Shared Preferences for S…  ( 7 min )

Quando trabalhamos com NestJS, é muito comum ver serviços injetando o ConfigService diretamente. Isso funciona bem, mas pode tornar os testes mais complexos e acoplar o código a detalhes de configuração. Vamos comigo enquanto escuto uma playlist de techno no youtube. Neste artigo, vou mostrar uma abordagem simples para desacoplar suas classes e facilitar os testes, injetando valores primitivos prontos via módulo. Um serviço de criação de contato que valida a data mínima poderia ser escrito assim: @Injectable() export class CreateContactService { constructor(private readonly config: ConfigService) {} execute(name: string, birthDate: Date) { const minDate = this.config.get('CONTACT_MIN_DATE'); if (birthDate < minDate) { throw new Error('Data inválida'); } re…  ( 6 min )

Sidekiq is pretty much the go-to solution for enqueuing jobs for background processing when working on a Ruby-based project. It's simple to implement, has a clear DSL, and is well-supported by common testing frameworks like RSpec. That being said, and I may be nitpicking, but the standard implementation examples do add a little extra overhead if you wish to be more flexible with your job business logic, and additional test setup is required. Given we want a little background job that updates a user's name and any other business logic needed (to keep the example simple), we could create a standard Sidekiq job with that logic and call it from our code as such: class UpdateUserJob include Sidekiq::Job def perform(user_id, name) user = User.find(user_id) user.update!(name: name) …  ( 10 min )

I’ve been noticing how quickly businesses and even individuals jump on new SaaS platforms for almost everything project management, communication, analytics, you name it. They’re fast to set up, affordable at the start, and packed with features. But here’s the thing: the more I use them, the more I realize how much we have to adjust our workflow to fit the tool instead of the other way around. Sometimes I wonder if that’s slowing teams down instead of making them more productive. On the flip side, custom-built software takes longer and costs more, but it seems to give more flexibility in the long run. It grows with the business, integrates better with existing systems, and doesn’t force you into using features you don’t need. I have a Question: If you’ve worked with both SaaS platforms and custom solutions which one do you feel actually brings more value over time? Do the short-term wins of SaaS outweigh the long-term control of custom software, or is it the other way around?  ( 6 min )

Microservices and asynchronous communication are powerful tools. They let our systems scale, stay responsive, and build fantastic user experiences. We break down big, clunky applications into smaller, manageable parts that talk to each other. It sounds like a dream, right? Most of the time, it is. But there's a sneaky design flaw lurking in many async microservice architectures. It's often invisible until it's too late. This flaw isn't about crashes or error messages; it's far worse. It's silently corrupting your data, chipping away at the very trust you place in your system. We’re talking about a design choice that, when mishandled, can make your data outright wrong. Imagine you have an online store. When a customer places an order, several things need to happen: reduce inventory, charge …  ( 10 min )

Why? If your company has an EDA license monitoring system, you have a lot of useful data available for analysis. And if you bought EDA tools but don't actively monitor license usage, you may want to check my earlier post. Now what do we do with this "big-data"? There most likely will be time gaps caused by infrastructure failures/maintenance, as well as evolution of suppliers and list of licenses over time, and this complicates manual analysis. With the advancement of AI/ML tools, you could now connect your Prometheus database with AI assist tool via what's called MCP: Model Context Protocol. This allows LLM to query your database, automatically load relevant and up-to-date information in the context window, and as a result LLM will be able to accurately answer questions about usage, tre…  ( 6 min )

On Day 36 of your #90DaysOfDevOps journey, we’re tackling an important part of Kubernetes: Persistent Volumes (PVs) Let’s break this down and walk you through both tasks: What are Persistent Volumes (PV) in Kubernetes? Kubernetes Pods are ephemeral — which means data inside a Pod is lost when the Pod is deleted or restarted. To persist data beyond the lifecycle of a Pod, we use: Task 1: Add Persistent Volume to Your Deployment Let’s go step-by-step. Create a Persistent Volume (pv.yml) apiVersion: v1 This creates a 1Gi volume using the hostPath /mnt/data on the node (local path for testing). Create a Persistent Volume Claim (pvc.yml) apiVersion: v1 This PVC will bind to the todo-pv if the specs match. Update your deployment.yml to use the PVC Here’s the updated Deployment with volume mounting: apiVersion: apps/v1 Make sure: Apply the files kubectl apply -f pv.yml Verify Everything kubectl get pv Look for STATUS: Bound on the PVC and Running pods. Task 2: Access Data Inside the Pod Connect to the Pod kubectl get pods # get pod name Verify Data Access cd /app/data cat You should see files created or used by your app. Optional: Test Persistence kubectl delete pod 2. A new pod will be created (Deployment ensures this). 3. Check if data is still present by repeating the steps to access /app/data. You have Created and attached a Persistent Volume.  ( 6 min )

Two weeks ago, I had the pleasure and honour of delivering a keynote at the (milestone!) 20th edition of FrOSCon in Sankt Augustin, Germany. My colleague David (one of the core developers on the Mastodon team) was one of the original founders of FrOSCon all the way back when it started, and the event is held near his home location, so it was a doubly wonderful opportunity for me to see him in person, and also to meet his family! The last time I was in Bonn was in 1988, back then on a school trip exploring the Rhineland, in what used to be known as West Germany. aside: I remember two things about that visit very distinctly – firstly, being in a group of youngsters that was closely tailed by security staff around a department store in Bonn, no doubt because shenanigans were afoot by some of…  ( 7 min )

Start with a vibe brainstorm session then dive in on the implementation. Do the complicated thing while the spark is hot. We leaned straight into two gnarly threads—prize mode and deeper Stripe integration—because future-me never has more energy than present-me. I’ll keep saying it: for Squares, the UI *is* the product. Nail the feel and everything else (emails, backend, automation) lines up behind it. That’s why we shipped the multi-game invite selector and left the email as a polite placeholder.

Problem A user needs to scale Amazon Bedrock’s Nova Pro foundation model to handle 2,100 requests per minute for high-traffic workloads. They’ve enabled cross-regional inference but hit a wall—provisioned throughput isn’t available in Frankfurt, and they’re wondering whether Ohio might solve the problem. The core pain: avoiding throttling at scale. The crux is twofold: Provisioned throughput isn’t everywhere. Not every AWS region supports it. Frankfurt (eu-central-1) is one such case. On-demand scaling has ceilings. Bedrock’s on-demand usage will throttle once you cross soft limits (requests per second/minute) unless you pre-negotiate with AWS service teams. So the real question: How do you push Bedrock Nova Pro past default throttles to reliably support thousands of requests per minute?…  ( 8 min )

I’ve been working on improving Libre, my anonymous social experiment, and just rolled out several important security and optimization changes: 1.Anonymous Authentication via Firebase – every user now has a unique anonymous session, preventing abuse while keeping the experience frictionless. 2. Sensitive Keys Removed – tokens (e.g., ipinfo) are no longer exposed on the client side. 3. Advanced Anti-Abuse Filtering – stronger detection for offensive content, spam, and injection attempts (XSS, SQLi, flooding). 4. Client + Server Validations – strict sanitization, input validation, and hardened Firebase Firestore rules. 5. No UX changes – users still just tap “Start being Libre” to join. 6. Scalability & Resilience – better protection against bots and malicious traffic. Libre stays simple for users but is now much stronger behind the scenes.

LangGraph is a framework for building stateful, reliable agent workflows. Instead of executing a single prompt-response cycle, LangGraph enables agents to operate as directed graphs, where each node represents a step, state is shared across the workflow, and execution can branch, pause, or persist. This article summarizes the core concepts, prebuilt utilities, and typical applications of LangGraph. The memory object that flows through the graph. Nodes read from and write updates to state. Managed through channels that define merge strategies: Replace → overwrite existing values. Append → add items (e.g., chat history). Merge → combine dicts/lists.

Hello Dev community! I am a Computer Science and AI student at IE Madrid. I joined DEV to become a part of a larger community of creators where I can learn and grow, as well as record my progress over the coming years. I really enjoy coding and challenging myself as much as possible, and I continue this attitude with everything in my life including hobbies like cooking and boxing! I plan to post anywhere from casual daily insights to projects and questions for the community every week! (PS This is also my first blog, please feel free to send any tips not only on code but anything else as well!) Today's Insight My next steps are to figure out GitHub and how to create a portfolio, update my LinkedIn and CV, and spiff up on my coding skills. Hopefully I can achieve all of this during the first week of school so I can apply to the good internships ASAP before they're all gone. (Somehow, some already ended). I find it frustrating that so many companies want interns already ready to graduate, or expect ten-million and one skills to apply, but there's really nothing to do except try to learn at least a few more to maybe stand out. I know a lot of us are in the same boat with this struggle, but maybe the more we begin to enter into jobs and internships, the more change will come! I'm off to planning how to manage all of this, I hope you all are having more luck than me! :3  ( 6 min )

The automation itch every dev gets I didn’t plan to automate my life. It started with a single annoying task copying Twitter DMs into Notion. Felt dumb. Repetitive. Manual. It was the kind of thing a script should do while I eat noodles and pretend I’m productive. Fast-forward a weekend and I had an entire AI-powered workflow stack: n8n doing the orchestration, Docker keeping it sandboxed, And an AI agent layer quietly making decisions while I slept.

Bitnami is deprecating their Kafka images, and ZooKeeper is being removed from Apache Kafka 4.0. Time to migrate to KRaft mode with Confluent's official images for a future-proof, simpler architecture.

The crypto world is buzzing about DeFAI, the fusion of Decentralized Finance (DeFi) and AI. Market projections suggest DeFAI could grow from $1 billion to over $10 billion by late 2025. But here's the thing most people miss: building truly smart AI agents for finance means keeping their strategies private. Otherwise, they're just expensive targets for MEV extraction. DeFAI combines DeFi protocols with AI-driven automation. Think of it like having a really smart financial advisor that can: Analyze thousands of data points in real-time Execute complex trading strategies automatically Optimize yield farming across multiple protocols Manage portfolio risks without human intervention…  ( 8 min )

Because your future self deserves better code reviews. Let’s be real: most developers nod politely when SOLID comes up, then continue writing 500-line classes that smell worse than week-old fried eggs. Here’s the thing: SOLID isn’t about pleasing your CS professor. It’s about writing code that your future self won’t want to rage-quit from after a single bugfix. Bad code means frustration, late nights, and way too much coffee. SOLID is a language that senior devs use to communicate across years of maintenance. When you see it in a project, you don’t need to crawl line by line like some code archaeologist digging through ruins. Instead, you can predict the system’s behavior, understand responsibilities, and trust that classes aren’t hiding surprises like a clown in a sewer drain. Follow it, …  ( 12 min )

Cloud Misconfigurations: The Hidden Door Hackers Love Cloud adoption is at an all-time high, with organizations shifting their infrastructure to platforms like AWS, Azure, and Google Cloud. But here’s the catch: as more businesses move to the cloud, misconfigurations have quietly become one of the biggest security risks out there. For hackers, misconfigured servers are like leaving the front door unlocked with a big welcome sign. They don’t need to break in; they just walk in. In this article, we’ll explore how cloud misconfigurations happen, the methods attackers use to exploit them, real-world cases, and—most importantly—what you can do to secure your cloud environment. A single misstep in cloud configuration can expose databases, applications, or even the entire infrastructure t…  ( 8 min )

When you first dive into backend development with Node.js, it doesn’t take long before you bump into Express.js. It’s practically the default framework for building web servers and APIs in JavaScript, and for good reason, it simplifies the otherwise clunky task of handling requests, responses, and routes. In this article, we’ll take a thorough look at Express: what it is and why it exists, how to set up a simple project, how routing works in practice, and a few must-know tricks to get you comfortable. This will lay the foundation for the next article in the series (Part 2), where we’ll unlock the real magic of Express: middleware. You might be thinking: “Wait, Node.js can already create servers, why do I need Express?” That’s true, but here’s what a basic raw Node server looks …  ( 8 min )

On a quest to learn about game development with the Godot Engine, I recently took on the 20 Games Challenge. This whole challenge revolves around the idea that finishing a series of small scoped projects of increasing complexity is better than not finishing a Dream Game™.

Why I Did This to Myself Invoices are like bosses: they all look different, they all demand money, and they all ruin your day. The Tech Stack (aka Weapons of Mass Frustration) - OCR → For turning “blurred coffee-stained PDF” into “blurred text file.” - Regex → Because nothing screams fun like 200-character patterns. - ML-ish GST Predictor → Basically a model that guesses taxes better than me on exam day. - Python + pandas → To wrangle the chaos into something that looks like data. How It Works You upload an invoice. OCR panics but spits out text. Regex plays “Where’s Waldo” with GST numbers. AI pretends to be an accountant. You get structured output and tax predictions. Bugs That Almost Broke Me OCR Hallucinations: Me: “That’s ₹1200.” Regex PTSD: The BTS Incident: OCR once read “18% GST” as “BTS.” Code Snippet: My Regex Therapy Session import re def extract_gst(text): pattern = r"\d{2}[A-Z]{5}\d{4}[A-Z]{1}[1-9A-Z]{1}Z[0-9A-Z]{1}" match = re.search(pattern, text) return match.group(0) if match else "No GST found, cry harder." invoice_text = "Invoice #123 GSTIN: 22ABCDE1234F1Z5 Amount: ₹1200" print(extract_gst(invoice_text)) # Output: 22ABCDE1234F1Z5 Results (Sort of) Structured PDFs? Works like a charm. Low-quality scans? Good luck, buddy. Predicts GST fairly well — which is more than I can say about me filing taxes. What’s Next Teaching it sarcasm so it can also roast invoices. Export to Excel/CSV (for those who still trust spreadsheets). Maybe SaaS — so small businesses can suffer too. Final Thoughts This project taught me: AI isn’t about intelligence.

I had a demo ruined by backend downtime. I was demoing my Little Black Book app — a React and Express project for storing, adding, amending, deleting, sharing etc. cocktail recipes. The frontend was loading fine, but when I tried to fetch the list of drinks from the API, the request just froze. No response. No errors. Just dead air. The worst part was I knew this happens. Before the demo, I’d even prepped for it. I opened the app, clicked around, made sure the backend on Render was awake. But the demo came late in the conversation, and Render’s free tier 15-minute inactivity limit quietly kicked in while we were talking. By the time I actually showed the app, the backend had gone to sleep. So the first request during the demo… just didn’t return. my demo was a long awkward fumbling around…  ( 7 min )

Searching for jobs can feel like a full-time job in itself. So I decided to do what any lazy developer would do... I automated it. 🚀 Too many platforms (LinkedIn, Indeed, remote job boards, etc.) Same repetitive filtering process every day Hard to keep track of new postings Instead of wasting my energy on job hunting, I wanted a workflow that does the boring stuff for me, only shows me relevant opportunities, and notifies me instantly. If you haven’t used it before, n8n is an open-source workflow automation tool. Here’s how my setup works: Visit the URLs of career pages or job boards, use the filters available on site and add the URL into a Google Sheet. The workflow fetches openings from those URLs, and includes/excludes jobs if the role title contains certain keywords. For each matching job, the workflow scrapes the full job description. An AI model analyzes the description and decides if the job is actually relevant. If it passes the check, I get a Telegram notification instantly. No more endless scrolling, just the jobs that actually matter to me. Saves hours of job hunting every week Never miss new opportunities Scales easily, I can add more job sources anytime Feels like I have a personal job-hunting assistant Watch the DEMO 🎥 https://youtu.be/KKYsuBKQ_No https://gist.github.com/Heapnotizer/82153323498bdf95765ce8232d0a960a 💬 Have you automated any part of your job hunt before?

Before we dive deep into today's blog, I want us to talk about what bits are. Bits are the smallest piece of information a computer understands. Bits only have 2 values; 0 or 1. Computers represent everything from symbols to text and numbers with 0's and 1's, and a combination of these 0's and 1's forms a binary number. Bitwise operators allow you to work directly with the individual bits inside the integer. Java provides; AND(&), OR(|), XOR(6^), NOT(~). When working with bits in programming, two operators you’ll often encounter are > (right shift). At first, they may look a little intimidating, but once you get the intuition, they’re actually very powerful and surprisingly easy to understand. The Left Shift Operator > The >> operator works the opposite way: it pushes all the bits in a number to the right, filling the empty spaces on the left with either zeros or the sign bit (depending on the language and whether the number is positive or negative). Example: int y = 20 >> 1; >> is like a quick way to divide numbers by powers of 2. Why Are Shifts Useful? Bit masking – Used to check or manipulate specific bits in a number. Efficiency – Shifts can multiply or divide by 2 much faster than arithmetic operations. Low-level programming – Essential in hardware control, graphics, compression, and cryptography. Quick Intuition Recap Once you see shift operators as shortcuts for multiplying and dividing by powers of two, they stop being scary and start becoming powerful tools. Whether you’re doing system programming, optimizing code, or just learning about bits, > will show up everywhere.  ( 7 min )

Introduction The Model Context Protocol (MCP) is a powerful way to expose your systems to AI agents. But a common mistake teams make is to take an API built for humans, auto-convert it to MCP tools, and expect agents to use it effectively. APIs designed for human developers follow a very different set of rules than APIs/Tools that serve AI agents in agentic workflows. What’s intuitive for a person is often overwhelming, inefficient, and error-prone for an LLM. If we want our agents to succeed, we need to design for them from the ground up — not just repurpose what we already have. Imagine you want to enable agents to use your flight booking system by converting the current APIs you have, and you ask your agent to find the cheapest direct flight to Paris in June, This is roughly the api c…  ( 8 min )

Place the order Calculate costing, pricing and discounts before saving Generate order number before saving Send emails to customer and store admin Produce notification sound in admin panel to get attention This is a typical example where you need to do multiple steps to complete a process.

Most developers know Django for its ORM, admin, and views. But there’s a feature hiding in plain sight that often goes underused: Signals. Signals allow different parts of your Django application to communicate with each other without being directly connected. In other words, they will enable you to trigger actions automatically when specific events occur within your app. If you’ve ever worked with event listeners in JavaScript, think of signals as Django’s equivalent. At the simplest level, a signal is just a notification system. When something happens—like a user registering, a model being saved, or an object being deleted—Django can “signal” that event, and you can attach functions that respond to it. Some practical examples include: Automatically creating a profile when a user signs up…  ( 7 min )

When working with .NET Framework MVC applications, I used to use bound view models, which let me use classes on the Razor templates very easily with the autocomplete feature. This was a default feature provided for .NET Framework by Visual Studio IDE. In the Razor views, we had to define a class as a model on top, and on the other hand, in the controller, we were forced to pass the instance of that class to the view. If passed a different class instance, it would throw an error telling this view required the instance of the defined class. Once this was done, we were able to access class with a variable called Model. This gave the autocomplete feature within Razor view. I was looking for the same thing in the Laravel ecosystem, but I found none. So I practiced a pattern I call ViewModels an…  ( 8 min )

We know that there are various types of error which we might come across in coding, they are broadly classified as following types: Error in the syntax such as initializing value without declaration, absence of semicolon etc are considered syntax error. When wrong logic is applied to the code, it is called logical error. This type of error do not cause any problem in compilation or execution but they perform the wrong task, i.e. the code doesn't behave in the expected manner. These are the errors that we do not realize until the code is run, i. e. we cannot view them at compile time as they occur at runtime. These errors can usually be treated and these are then called exceptions. So exception in java is basically a resolvable event the disrupts the normal flow of program. common exceptions that we come across are: NullPointerException ArithmeticException -ArrayIndexOutOfBoundException -IllegalArgumentException -NumberFormatException So assume following code, in this I've declared an array, and its asking the user to enter an index to be retrived. As the length of array is 5 so entering index til 4 is valid and if index greater than 4 is entered in normal circumstances it would give error. But we do not want our program to crash over such pity things such as invalid input so we perform exception handling, where we make two blocks a Try block that contains the code that might cause error, by this we tell the compiler to try doing that part of code, and if it throws an error it is given to the Catch block which catches the error by its type mentioned in the parentheses and then does the action that shows us that the error has been dealt. Finally block that is executed whether any error arise or not, the only time it is not executed is when there's an error in the finally block as well, or when it contains a dead thread or when we use System.exit().  ( 6 min )

Why is your GPU cluster idle While organizations obsess over CPU and memory optimization in their Kubernetes clusters, a far more expensive problem is quietly destroying budgets: GPU underutilization. The average GPU-enabled Kubernetes cluster runs at 15-25% utilization, but unlike CPU overprovisioning, which can waste thousands of dollars per month, GPU underutilization can burn through tens or hundreds of thousands. Consider this: a single NVIDIA H100 instance costs $30-50 per hour across major cloud providers. An underutilized cluster with 20 GPUs running at 20% utilization incurs approximately $200,000 in annual compute costs alone. Yet most organizations lack the monitoring, processes, and architectural strategies to address this systematic waste. The challenge isn't just about reso…  ( 8 min )

When starting your journey in Data Science or Machine Learning, one of the first libraries you’ll encounter is NumPy. Why? Because pandas, scikit-learn, TensorFlow, and PyTorch are all built on top of NumPy. If you understand NumPy arrays, you’ll have an easier time working with any data library in Python. In this post, we’ll cover the essentials: creating arrays, indexing, reshaping, performing operations, and using useful functions.

Introduction Working with Golang is always fun and satisfying. But when it comes to scaling your application on a distributed computing infrastructure, you start to feel the real pain. To reduce such pain, numerous models and patterns were discovered. Some are cloud native (Kubernetes for example), while others need to be implemented at the architectural level. One such model is called Actor Model. We'll dive deep into what Actor Model is in this blog. An actor is an independent unit that encapsulates its own state and behavior. Actors do not share state directly; instead, they interact only through message passing. One major advantage of Actor Model is it's fault tolerant nature. Since each actor is isolated and interacts only through asynchronous messages, an anomaly or failure in one…  ( 9 min )

Clean coding principles aren’t just buzzwords—they’re what separate junior developers from professionals who write maintainable, scalable, and reliable software.

First gather a corpus of text. Let's call it the entire public internet. Next train a Large Language Model (LLM) against this corpus and you will get a system like Grok, Gemini or ChatGPT which approximates Artificial Intelligence (AI). Now sell this LLM to people who use it to generate content they later post to the internet. The moment you make available the first generation of your LLM, you will immediately begin developing the second generation of your LLM in order to remain competitive in the AI arms race. Gather a new corpus of text. A fresh snapshot of the entire public internet. Train your new LLM against this new corpus, knowing that it contains some non-zero percentage of LLM generated content produced by users of the first generation of your product. Now sell v2 of your LLM to more people who use it to generate more content they later post to the internet. You can see where this is going. Each new generation of your LLM is trained on a higher percentage of LLM generated inputs as the last. This leads to Macro self-training where large language models are inadvertently affecting the quality of successive generations by feeding their own outputs (and the outputs of other models) into the inputs of the newer generation of models. However inaccurate LLMs are today, we should expect them to become more deranged and hallucinatory over time. Not less. When developing the nuclear bomb, some scientists worried it might ignite the atmosphere and end the human race. This concern did not stop them from detonating the most destructive device ever constructed. If you think legitimate concerns regarding the safety of AI will be heeded, you don't understand the macroeconomics. These multi-billion dollar models are going to choke on their own excrement spraying trash across the entire internet and crash the global economy full speed into the brick wall that is The Ouroboros Problem.  ( 6 min )

Flutter has always sparked strong opinions in the dev community. Some swear by its speed and cross-platform magic, others dismiss it as a Google experiment that will eventually fade away. But here we are in 2025, and the question is louder than ever: 👉 Is Flutter still worth learning in 2025? I did some digging, went through recent updates, community trends, and job market stats. Let’s break it all down. Flutter isn’t some abandoned side project. In fact, it’s still shipping major releases in 2025: 3.29 (Feb 2025) → performance improvements and better tooling. 3.32 (around Google I/O) → Web improvements and Impeller renderer polish. 3.35 (Aug 2025) → Hot reload for web finally became stable and buttery smooth.

Python’s Next Chapter A massive Python Developers Survey of over 30,000 coders shows the language keeps evolving—newer tools and modules are reshaping how we build apps. While Python remains king in data science, web dev and automation, it’s also carving deeper niches with libraries like FastAPI, Pandas and NumPy. Compared to 5–10 years ago, we’re seeing a clear shift toward type hints, static analysis and better packaging workflows, making projects easier to maintain and share. On the tooling front, PyCharm still leads the pack, but VS Code and new cloud-based IDEs are gaining ground. Packaging got a glow-up too, with more folks using Poetry and Hatch to streamline dependencies. Demographically, Python’s user base is younger and more global than ever, driving fresh innovation in AI, ML and beyond. Overall, the survey paints a picture of a maturing ecosystem that’s ready for whatever’s next. Watch on YouTube  ( 6 min )

Back to basics. Third chapter of The Rust Programming Language is about common concepts, such as variables, types, functions, and comments: we’ve already seen all of them in the previous episode, but I’ll go deeper this time. Here’s the full list of primitives you must be aware of. Rust, like any other programming language, has some reserved keywords that you can’t use to name variables, etc.; the book lists in an appendix all the keywords currently in use or that could be used in future releases. What’s interesting here is the raw identifier r# which let you use them anyway like r#keyword. I’ve already noticed it last time: variables are immutable by default in Rust, even though they are all called let. This can be confusing, coming from JavaScript, where we distinguish let from const.

You've mastered Compose basics. You chain modifiers like a pro: padding here, background there, maybe a click handler at the end. It feels natural, almost meditative. But, identical UIs can perform drastically differently based solely on how you order and structure your modifiers. Think of it like cooking. You can make the same dish using different techniques, one way leaves you with smooth workflow and minimal cleanup, another creates unnecessary mess and takes twice as long. Same end result, completely different efficiency. Consider this everyday chat interface element: // Looks perfectly reasonable, right?

The Problem Last month, our team started getting complaints that our Next.js application felt sluggish. Users were experiencing slower navigation between pages, even though we hadn't made any major changes recently. The app was noticeably slower in production environments. So I started investigating this performance regression and what I discovered was a subtle but impactful issue with how Next.js handles prefetching for dynamic routes. Our application uses Next.js 15 with App Router, and we were using the standard Link component which handles prefetching automatically. Initially, this seemed fine—prefetching should make navigation faster, not slower. So why were we seeing the opposite? The breakthrough came when I examined our recent routing changes. We had recently implemented internat…  ( 9 min )

I’ve worked on SaaS products where the Settings page quietly swallowed the whole experience. Not in one dramatic release – in gentle increments. A toggle here to “keep options open”, a checkbox there to “unblock a stakeholder”, a dropdown to “cover an edge case”. It feels generous in the moment. It reads like hesitation later.

Beyond Code: Why UX/UI Design is Essential for Every Developer Think about it: you can build the most performant, bug-free, and elegantly architected backend system, but if the user interface is confusing, clunky, or frustrating, your users will simply abandon it. Their experience dictates the success of your project, regardless of the brilliance under the hood. It’s time for developers to step out from behind the command line and embrace the human element of their creations. The Developer's Shifting Role: More Than Just Code Embracing UX/UI principles allows developers to be more proactive. Instead of just implementing designs, they can contribute valuable insights during the design phase, flagging potential technical challenges or suggesting more user-friendly alternatives from an implementation perspective.

“A portfolio isn’t just a website. It’s your story, your brand, your invitation to connect.” – Every web developer ever (including me) Back in early 2022, my developer journey started with a humble, single-page website: a few lines of HTML, home-baked CSS, and a hint of JavaScript. I hosted it on GitHub Pages at RD's Portfolio. It did the job: showcasing projects, sharing my bio, and providing a contact method. But as my skills (and ambitions) grew, the limitations of this static site became glaringly obvious. Fast forward to 2025.

Why workloads are fragmenting, edge is rising, and centralized cloud is quietly unraveling Press enter or click to view image in full size I used to think cloud centralization was the cheat code. Just deploy everything to us-east-1, toss it behind an API Gateway, slap a global CDN on top, and call it scalable. That’s what all the blog posts said, right? “Don’t worry about infra. Just use the cloud.” But somewhere between the $400 surprise bill, the cold starts, the 500ms latency to users in Singapore, and my fifth “is this region down?” panic spiral… I started to wonder: Is this what modern infrastructure is supposed to feel like?

Python library triggon can dynamically switch values and functions, and it helps clean up your code by reducing the need for if statements. I'm going to introduce its features with two simple examples! import random from triggon import Triggon, TrigFunc F = TrigFunc() # Wrapper for delayed execution tg = Triggon("num", new=F.random.randint(1, 100)) def func(): # If 'num' is active, switch the value from 0 to random.randint(1, 100) num = tg.switch_lit("num", org=0) print(num) func() tg.set_trigger("num") # Activate the "num" label func() tg.revert("num") # Switch to the original value func() # == Output == 0 79 (random number between 1 and 100) 0 switch_lit() automatically executes the function if it is delayed with TrigFunc.

Most founders rush into building an MVP. But here’s the truth: an MVP isn’t just a product, it’s a test of your hypothesis. Skip a few critical steps, and you risk wasting time, budget, and trust. Here’s what to do before you write a single line of code. 1) Define the Problem, Not the Product Your job isn’t to build features, it’s to validate a problem worth solving. 1. Create mockups, landing pages, or even run “manual MVPs.” 2. Collect signals that people want the solution before you ship it. 2) Minimum Lovable Product > Minimum Viable Product “Viable” is too cold. Your MVP should be usable and memorable. Delight creates stickiness. 3) Flip the Process: Demo → Sell → Build Instead of Build → Demo → Sell, try this: Sketch solutions (Lean Canvas, mockups) Validate with demos, pre-orders, or feedback Build what people already proved they want This cuts down on risk and prevents feature bloat. 4) Be Lean. Be Metrics-Driven. Track early signals: Who’s clicking? Who’s signing up? What’s converting? If something doesn’t move the needle, cut it quickly. Your MVP’s job is to collect learning, not to ship a perfect product. TL;DR An MVP isn’t about speed alone. It’s about validating with empathy. Build something small, lovable, and data-driven — and you’ll have the right foundation to scale.  ( 6 min )

Web development is more than just making things “look good.” Under the hood, the way you structure your HTML has a huge impact on how search engines and assistive technologies (like screen readers) interpret your content. This tutorial covers: ✅ What Semantic HTML is ✅ How to use it properly ✅ Why it improves SEO ✅ Why it improves accessibility ✅ Examples with code Semantic HTML refers to using HTML tags that carry meaning about the type of content they contain. Examples: → Introduces a page or section header → The primary content of the page → Independent, self-contained content (like a blog post) → Navigation links → Footer information Non-semantic tags (like and ) tell nothing about the content. They are useful for styling/layout but don’t provide meaning. Think of semantic HTML as “HTML that explains itself.” Helps Google and other search engines understand your content. Improves rankings because crawlers know which parts are important. Increases chances of getting rich snippets in search results. ♿ Accessibility Screen readers rely on semantic HTML to announce content properly. Example: A element signals “navigation menu,” making it easier for users to jump around the page. Keyboard navigation becomes smoother. html My Blog Home | Articles | Contact First Post This is my first article about web development. © 2025 My Blog  ( 6 min )

As developers, we often take text processing for granted—until we encounter languages that break our assumptions. Recently, I dove deep into the complexities of building a reliable Japanese text counter, and the journey revealed some fascinating challenges that go far beyond simple character counting. Most text counters work perfectly for Latin-based languages, but Japanese presents unique challenges: Multiple Writing Systems Japanese uses three different scripts simultaneously: Hiragana (ひらがな) - phonetic characters Katakana (カタカナ) - typically for foreign words Kanji (漢字) - logographic characters borrowed from Chinese A single sentence like "私はプログラマーです" contains all three systems, and each has different counting implications.

The first chapter in a 7-part series on mastering ChatGPT through 400+ real developer use cases. Based on 140+ real prompt workflows. You’ve probably asked ChatGPT to write code for you. You’ve debugged an error, rewritten a function, maybe even built half a project with its help. But if you’re anything like me (or the 140+ devs I studied), you’ve also wondered: “Is this how I’m supposed to use it?” “Why does this feel fast, but also… kinda empty?” “Am I getting better — or just better at copy-pasting?” This is Part 1 of The Dev’s AI Vault, a 7-part series built from over 400 real-world developer use cases including 140+ detailed prompt workflows.

Lost in Notes If you're like me, your Obsidian vault has grown into a sprawling collection of hundreds of notes scattered across dozens of folders. I haven't fully utilised the tags function and haven't linked notes efficiently. So the majority of my notes are floating orphan nodes.

Programming isn’t just about writing code—it’s about thinking clearly, structuring logically, and organizing effectively. Just like planning a road trip involves choosing the route, stops, and timing, programming requires a well-thought-out sequence of decisions and actions. This module introduces the core logical processes and the importance of organization in programming. Logical processes are the building blocks of programming. They define how a program flows, reacts, and repeats actions. These processes aren’t separate from code—they are the code’s structure. Sequences Definition: A sequence is a set of instructions executed in a specific order. Real-Life Analogy: Morning routine → Brush teeth → Shower → Eat breakfast.

Your phone just suggested the perfect playlist for your mood. Your navigation app found a route that saved you twenty minutes. Your banking app approved a transfer in seconds. Amazing what a few lines of code can do, isn't it? But here's something that might surprise you: behind each of those helpful moments was a decision about what kind of AI we want in the world. And those decisions – made by programmers, designers, and executives you'll never meet – are quietly shaping how you live, work, and connect with others. The good news?

Introduction If you follow the stock market, you may have heard of the VVIX. Many traders and investors often check the VVIX current value to understand market volatility. Simply put, VVIX measures the expected volatility of the VIX, which itself measures fear in the S&P 500. In other words, it’s the “volatility of volatility.” By knowing the VVIX current value, traders can get an idea of how unpredictable the market might be and adjust their strategies accordingly. What is VVIX? The VVIX is a volatility index created by the Chicago Board Options Exchange (CBOE). While the VIX shows how volatile the S&P 500 is expected to be, the VVIX shows how volatile the VIX itself is expected to be. High VVIX values → Expect bigger swings in the VIX and more market uncertainty. Low VVIX values → Market…  ( 7 min )

Introduction Artificial Intelligence (AI) is changing how software gets built. From auto-completing lines of code to generating entire functions, tools like GitHub Copilot and ChatGPT are redefining productivity in programming. They promise speed, efficiency, and fewer errors. But behind the hype lies an uncomfortable question: Will AI eventually replace developers altogether? There is nothing wrong with using better tools. Ignoring them just makes your work harder for no reason. Developers have always embraced innovations such as compilers, frameworks, and cloud services that made coding more efficient. AI is simply the next step in that evolution. The real danger is not that AI will replace developers, but that developers might replace their own thinking with AI. Writing code isn’t jus…  ( 8 min )

When building or integrating APIs, you’ll often come across two terms that sound similar: callbacks and webhooks. Both involve one system sending data back to another, but they serve different purposes. Let’s break them down. A callback is a URL you provide to an API when making a request. The API uses that URL to send back the result of that specific request. Triggered by: A request you initiated. Used for: Asynchronous responses. Scope: Only for the request that included the callback URL. 👉 Example: https://yourapp.com/ft-callback). Once the bank finishes processing, it POSTs the result (success or failure) to that callback. { "transactionStatus": "SUCCESS", "amount": 100, "transactionReference": "CSS472TCP" } ✅ Purpose: Tie back the outcome of a request you made earlier.

Pattern: Two Pointers & Fast-Slow Pointers 🔹 Why This Pattern? Two Pointers (and its fast-slow variant) is one of the most frequently tested patterns across FAANG interviews. It appears in: Arrays → sorted arrays, pair-sums, container problems. Strings → palindrome checks, valid substring problems. Linked Lists → cycle detection, middle node, removing N-th node. Intervals → merging, intersecting timelines. It is optimal in problems where brute force = O(n²), but two pointers optimize to O(n). Best for sorted arrays and string palindrome checks.

Netflix: applies it in streaming/log analysis contexts. Used when window length is known (like k). int slidingWindowFixed(int[] arr, int k) { int left = 0, sum = 0, maxSum = 0; for (int right = 0; right k) { sum -= arr[left]; left++; } maxSum = Math.max(maxSum, sum); } return maxSum; } Used…  ( 6 min )

Before Oracle Database 23ai, the awrsqrpt.sql script was commonly used to analyze the evolution of a SQL statement’s execution plan, plan statistics, CPU usage, I/O, and elapsed time over a specified period. However, this approach had two main limitations: It required specifying two specific AWR snapshots. The information provided in its report was relatively limited. Sample Output of awrsqrpt.sql: The REPORT_SQL function provides a graphical report in HTML format, allowing for the analysis of: Execution plan history Cursor sharing information Optimizer statistics history Index details And more REPORT_SQL Function: SQL> desc DBMS_SQLDIAG.report_sql Parameter Type Mode Default? --------- -------- ---- -------- (RESULT) CLOB SQL_ID VARCHAR2 IN DIRE…  ( 7 min )

IT asset loss is a growing concern for many businesses. IT asset discovery is the first step in preventing these problems. It helps you identify, track, and manage every piece of technology connected to your network. From hardware like computers and servers to software and cloud-based tools, IT asset discovery ensures you always know where your assets are and who is using them. IT asset discovery is the process of identifying and tracking all the technology resources within an organization’s IT environment. This includes everything from computers, servers, and mobile devices to software applications and network infrastructure. The goal of IT asset discovery is to create a comprehensive, real-time view of all IT assets. In simple terms, it’s about knowing what devices and software your busi…  ( 17 min )

Greedy algorithms are all about making locally optimal choices at each step, hoping to reach a globally optimal solution. Amazon frequently uses this pattern in scheduling, interval, and resource allocation problems. Use Greedy when: A problem involves optimization (maximize/minimize something). The problem can be solved by sorting + local decision-making. Once a choice is made, it doesn’t need to be reconsidered (no backtracking). 👉 Amazon-style phrasing: n activities with start and end times. Select the maximum number of non-overlapping activities. import java.util.*; public class ActivitySelection { static class Interval { int start, end; Interval(int s, int e) { start = s; end = e; } } public static int maxActivities(List activities) { a…  ( 7 min )

Amazon loves Trie-based problems because: They simulate autocomplete search, spell-checkers, URL routing, and dictionary lookups. Tries are highly efficient for prefix-based queries. 👉 Amazon-style phrasing: insert, search, and startsWith. class TrieNode { TrieNode[] children = new TrieNode[26]; boolean isEndOfWord; } public class Trie { private TrieNode root; public Trie() { root = new TrieNode(); } // Insert word public void insert(String word) { TrieNode node = root; for (char c : word.toCharArray()) { int idx = c - 'a'; if (node.children[idx] == null) node.children[idx] = new TrieNode(); node = node.children[idx]; } node.isEndOfWord = true; } // Search word public bo…  ( 8 min )

Amazon interviewers love matrix/grid problems because they test: Traversal strategies (row-wise, column-wise, diagonals, spiral). Boundary handling. In-place transformations. BFS/DFS usage for pathfinding. These problems simulate warehouse navigation, routing, and optimization problems that Amazon faces in real-world systems. 👉 Amazon-style phrasing: n x n matrix, rotate it by 90 degrees clockwise in-place. public class RotateImage { public static void rotate(int[][] matrix) { int n = matrix.length; // Step 1: Transpose for (int i = 0; i < n; i++) { for (int j = i; j < n; j++) { int temp = matrix[i][j]; matrix[i][j] = matrix[j][i]; matrix[j][i] = temp; } } // Step 2: Reverse…  ( 8 min )

Amazon loves to test whether you can use bits for optimization instead of relying on brute force or extra memory. space-efficient, fast solutions to problems involving: Unique numbers Parity checks Power-of-two checks Subset generation Bit manipulation means solving problems using binary representation and operators like: & (AND) | (OR) ^ (XOR) ~ (NOT) > (right shift) 👉 Why Amazon asks this: Very efficient (O(1) per operation). Saves memory (no extra DS needed). Trains you to think at a low level. 👉 Amazon-style phrasing: public class SingleNumber { public static int singleNumber(int[] nums) { int result = 0; for (int n : nums) { result ^= n; // XOR cancels out duplicates } return result; } public static void main(…  ( 7 min )

Amazon loves ranking, recommendation, and selection problems—whether it’s finding the top-selling products, most visited pages, or most frequent queries. These problems usually need priority queues (heaps) or bucket sorting. This is where the Top-K Elements Pattern shines. The idea is to efficiently find the K largest/smallest/frequent elements without sorting the entire dataset. Sorting takes O(n log n). With a min-heap of size K, we can reduce this to O(n log k). In some frequency problems, bucket sort can achieve O(n). When Amazon uses this pattern: Product ranking (top K sellers). Log analytics (most frequent IPs or queries). Performance optimization (K nearest servers, K largest numbers). 👉 Amazon-style phrasing: nums and an integer k, return the k most frequent elements. import java…  ( 8 min )

If you’ve ever used a tool like Slack, Trello, or even Google Docs, you’ve already experienced SaaS in action. It is hard to imagine modern work without it. According to a recent report by BetterCloud, nearly every company, almost 99%, now depends on at least one SaaS product to get things done. But what we don’t often see is the structure underneath, the software architecture that holds everything in place. And truthfully, this part can make or break a product. It is not just about writing clean code or choosing the latest tech stack. It is about building something that can grow, adapt, and survive, even under pressure. The choices made early on about architecture will affect everything from how quickly you can release new features to whether your app crashes when the number of users incr…  ( 13 min )

👉 When Amazon asks for problems involving running medians, balancing data, or minimizing differences, Two Heaps Pattern is the go-to approach. Maintain two heaps: Max-Heap → stores the smaller half of numbers. Min-Heap → stores the larger half of numbers. Balancing ensures: Max-Heap size ≥ Min-Heap size Difference in size ≤ 1 ⚡ This allows quick median or balancing decisions in O(log n). 👉 Amazon-style phrasing: import java.util.*; public class MedianFinder { private PriorityQueue maxHeap; // lower half private PriorityQueue minHeap; // higher half public MedianFinder() { maxHeap = new PriorityQueue(Collections.reverseOrder()); minHeap = new PriorityQueue(); } public void addNum(int num) { if (maxHeap.isEmpty() || num…  ( 8 min )

Managing Branches and Merging in Git In this exercise, I worked on the official project repository located at /opt/official.git. The objective was to create a new branch, add a file, merge changes back into the master branch, and push everything to the remote repository. This task ensured proper branching workflows, safe integration of new changes, and clean synchronization with the remote repository. Below are the detailed steps I followed to complete the exercise. Note: I used sudo for this exercise since the respective directories were owned by root rather than the user natasha on the storage server. Alternatively, chown could be used to change ownership. The project repository had already been cloned under /usr/src/kodekloudrepos/official. I moved into this directory to begin the work: cd /usr/src/kodekloudrepos/official Before creating a new branch, I switched to the master branch and updated it with the latest changes from origin: sudo git checkout master sudo git pull origin master A new branch named xfusion was created from master: sudo git checkout -b xfusion The provided index.html file, located at /tmp/index.html, was copied into the repository root directory: sudo cp /tmp/index.html . The file was staged and committed into the new branch: sudo git add index.html sudo git commit -m "Add index.html file" The xfusion branch was pushed to the remote repository to keep origin updated: sudo git push origin xfusion I switched back to master and merged the changes from xfusion: sudo git checkout master sudo git merge xfusion Finally, the updated master branch was pushed back to the origin: sudo git push origin master The index.html file is now part of the repository in both the xfusion branch and the master branch. Both branches were successfully pushed to the remote origin. The task validated Git best practices: creating feature branches, committing changes safely, and merging them back into the main branch.  ( 7 min )

💡 Every AI headline sounds the same: "This new model has 70B parameters" or "Trained on 2 trillion tokens". Sounds impressive, right? But what does that actually mean for your business - and more importantly, your budget? Let’s break it down with a practical lens. 🚀 Meet ShopEase: A Startup at a Crossroads On a small AI model, it worked fine for FAQs. Not so fast. 🧩 What Parameters Really Mean (Without the Jargon) GPT-2 → 1.5B parameters. 175B parameters. 1.76 to 1.8 trillion parameters. Training GPT-3 reportedly cost $4.6M in compute. That’s before you even use it. So when you hear "70B parameters", don’t think "smarter". Think "heavier to run, more expensive to maintain". 💵 Tokens: The Meter That Never Stops Running you still pay per token when you use it. GPT-4o-mini: ~$0.15 per 1M tokens. 👉 That’s a 200x difference in cost. Back to ShopEase: Their chatbot handles 1M queries/month. On GPT-4o-mini → $150/month. Same queries. Same customers. But $29,850 of “AI tax” each month. 📉 The Hidden Trap of Scaling Blindly Scaling without strategy can: Burn budgets (AI bills growing faster than revenue). Add latency (customers waiting 5+ seconds per answer). Hurt ROI (extra cost may not mean happier customers). ShopEase realized: instead of jumping to a mega-model, they could fine-tune a medium model with their support transcripts for far cheaper — and better aligned to their domain. ✅ Key Takeaway Parameters = capacity (how much the AI can "know"). Tokens = cost (every interaction charges you). Bigger ≠ automatically better. If you don’t understand these two levers, your AI project isn’t a strategy - it’s a gamble. 👉 Coming next in this series: "Small vs Medium vs Large Models: The Trade-Offs That Matter."

What’s worse than a date parser throwing an error? One that doesn’t—and gives you the wrong answer. 💀 Imagine this: "12/01/2024" → interpreted as January 12th, when the user meant December 1st. No warnings. No logs. Just bad data flowing through your systems. This is why we added confidence scoring to our Date Normalizer API. It’s not a gimmick—it’s a foundational feature that turns parsing from a black box into a transparent, predictable process. Date strings are messy. They come in: Different regions: US vs EU (12/01/2024 vs 01/12/2024) Mixed separators: 07-04-25 vs 07/04/2025 Natural language: "next Friday at 3pm", "in 3 hours" Time zones: PST, UTC, offsets like +05:30 Traditional parsers take a “best guess” approach.

Web browsers perform a fascinating and complex series of steps to transform raw HTML code into the visually rich and interactive web pages we use every day. Understanding browser rendering and HTML parsing offers valuable insight for web developers aiming to optimize performance and user experience. Here's a deep dive into the core stages involved in how browsers handle and render HTML content. The rendering process starts when a browser requests an HTML document from a web server. As HTML bytes stream in, the browser begins parsing them immediately — this parsing converts markup into an internal data structure called the Document Object Model (DOM). The DOM is a hierarchical tree representation of every HTML element on the page, capturing their relationships and nesting. Tokenization: The…  ( 7 min )

And the reason isn’t the tools themselves — it’s the way humans actually work. The Problem With “All-in-One” Tools Feature bloat → Instead of doing one thing exceptionally well, all-in-one tools do five things “okay.” Notion, Trello, ClickUp… and the Same Cycle Or ClickUp: it does tasks, docs, goals, dashboards… but the more you add, the slower and more overwhelming it becomes. Or Trello: great for visual project boards, but once you start needing docs, AI help, or team comms, it starts to feel like just one piece of the puzzle again. Each of these tools works. But none of them work for everything. What Actually Works: The Hybrid Stack For me, that looks like: Notion → Knowledge base + long-term planning. Google Calendar → Hard deadlines + time blocking. Slack/Discord → Team comms. FlowTask → Quick execution. One prompt → structured workspace with tasks, deadlines, and docs, plus a context-aware AI assistant (FlowBot) that helps inside the work itself. Instead of forcing everything into one mega-tool, I use the right tool for the right job. Why Flow Over Features Wins The best tool is the one that gets you from idea → execution with the least friction. “All-in-one” sounds good on paper, but in real life, flexibility and speed matter more. Final Thoughts For me, it’s no longer about cramming everything into one app. It’s about picking a small stack that works together — and staying focused on the actual work.  ( 7 min )

You're building your WordPress site and need icons. Simple enough, right? Then you realize your theme has maybe three decent icons, and they don't match your design at all. So you search for icon plugins. Suddenly you're drowning in options. Some promise thousands of icons but haven’t been updated in years. Others work great until they clash with your theme or break the block editor. A few look perfect but cost more than your hosting plan. We've analyzed some of the best WordPress icon plugins to find the best options for you. This blog covers the best WordPress icon plugins, their features, and the installation methods. Let’s take a look! Before you pick an icon plugin for your WordPress site, it's better to know what really matters in an icon plugin. Here are some questions to ask when c…  ( 10 min )

Machine learning is everywhere today, from Netflix recommendations to fraud detection . One of the most important techniques behind these systems is supervised learning, and within that, classification shines as one of the most practical approaches. In this article, I’ll break down: ✨ What supervised learning is ✨ How classification works ✨ Common models for classification ✨ My personal views and insights ✨ Challenges I’ve faced along the way Supervised learning is a type of machine learning where the model is trained on a labeled dataset. Inputs (features): The data we feed into the model. Outputs (labels): The known answers we want the model to predict. Think of it like teaching a student with flashcards: you show the input (a picture of a cat) and the correct label (“c…  ( 7 min )

Docker is a well known containerization tool, which most of us have either used it or have heard of it. Even though docker is used by many and is widely known about, there seems to be a lot of misconceptions floating around regarding it. Please note that this is not a docker tutorial, but a dive into what docker is and how it works under the hood. Before learning more about docker itself, let's first learn what a container is. A container is an isolated environment that contains the application code, required packages, tools, configuration and other requirements so that the packaged software can be run anywhere and can be perfectly recreated. So what's wrong with traditional methods? Due to difference in environments like operating system (Windows, Linux, MacOS, etc.), binary versions, de…  ( 12 min )

When it comes to productivity, we’ve reached a paradox: we’re overloaded with productivity tools. Notion, Trello, ClickUp, Todoist, Asana — they’re all excellent, yet sometimes, using them feels like another task on my to-do list. I’ve often caught myself setting up pages, creating templates, color-coding tags… instead of actually working. It made me realize: productivity tools should reduce friction, not create new layers of it. The Hidden Cost of Over-Customization This is where I think the next wave of productivity lies: zero-setup workflows. From Idea → Workspace, Instantly FlowTask) that takes a different approach: you type one prompt, like “Launch a podcast”, and it generates a ready-to-use workspace — with tasks, deadlines, notes, even content prompts. It feels less like “setting up a system” and more like jumping straight into execution. Instead of thinking “How should I organize this?” you immediately start doing it. Context is King: Enter AI That Knows Your Work That’s why I added a feature (FlowBot) that lives inside the workspace itself. It reads the page you’re on and responds based on that content only. Example: I dumped a contract draft into a workspace and asked it, “Flag risky clauses.” It highlighted three and explained why. That’s not just convenience — that’s context. Why This Matters for Productivity Enthusiasts Less setup → more execution. AI embedded into flow → no more app-hopping. Tailored workspaces → aligned with specific goals, not generic templates. I don’t think FlowTask (or any single tool) will “replace Notion.” 👉 My takeaway: the future of productivity tools isn’t “more features.” It’s less friction.  ( 6 min )

The Psychology of Prompts: Why Wording Changes Everything Jaideep Parashar ・ Aug 28 #ai #beginners #productivity #webdev  ( 6 min )

Introduction When you deploy an ec2 instance or any server instance, it defaults to SSH in port 22. You already know it, so do the whole world and all of the hackers. So, most of the automated attacks start by scanning the known ports, say 22 for SSH. One of the many ways to mitigate that is to change the port to a different port. Yes it won't make it bulletproof, but it will surely reduce the chances of brute force attacks. This method is applicable for all kinds of servers, including your Virtual Machines, but since I have an aws cloud account, I will use that, you can just use GCP Compute instance, Azure VM as well. In simple words, it means hiding something from the attackers, believing if the attackers can't see they can't exploit. Kind of removing your door to an unexpected loca…  ( 7 min )

🎬 "Ever wondered why your app’s data disappears when you stop a container? In this episode, we uncover Docker Volumes — your key to persistent, reliable, and sharable data storage." By default, Docker containers are ephemeral — which means: When the container stops, its filesystem is wiped. All your app logs, databases, and uploads? Gone. 🫠 This is great for clean environments… but not if you need data to stick around. Enter: Docker Volumes. A volume is a special folder outside the container, managed by Docker. Think of it like: A USB drive you plug into your container When the container is deleted, the USB (volume) stays intact You can re-attach it, share it across containers, and even back it up. docker run -d \ --name mysql \ -e MYSQL_ROOT_PASSWORD=mysecret \ -v mysql-data:/var/lib/mysql \ mysql:latest ✅ This creates a volume mysql-data that stores the DB. docker volume ls docker volume inspect mysql-data docker volume rm mysql-data docker volume prune Type Use Case Named Volume Long-term data (MySQL, logs, uploads) Bind Mount Dev mode (sync local folders) docker run -d \ -v $(pwd):/app \ -w /app \ node:18 \ npm start ✅ Any change you make locally reflects inside the container in real-time. Use named volumes in production Use bind mounts for live development Clean up unused volumes regularly In Episode 7, we’ll explore: How containers talk to each other Networks, bridges, ports, and real examples (Node + DB) Did you try volumes in your app yet? Still confused between named volumes and mounts?

“I quote others only in order the better to express myself.” *Context & Reflection Michel de Montaigne, the French Renaissance thinker credited with inventing the personal essay, penned this powerful line in his work "Of the Education of Children." It's a reminder that quoting isn't mimicry — it’s a method of understanding, refining, and voicing our own ideas more clearly. In tech and writing—especially when crafting tutorials, documentation, or personal blogs—we often lean on external sources. But Montaigne’s insight is timeless: we quote not to borrow authority, but to clarify what we ourselves are trying to say. Cite as Context, Not Crutch: When quoting, use the source to support or illuminate your perspective—not to replace it. Frame with Your Voice: Introduce and comment on quotes. Don't let them speak for you—let them speak with you. Use Sparingly to Strengthen: One powerful quote in the right place can elevate your point more than several filler references. Add Reflective Commentary: Ask yourself, “Why does this quote resonate with me?” Then share that thought. We all stand on the shoulders of those before us. But it’s our own vision that matters most. Montaigne reminds us that quoting is a creative act—when it helps express something only you can say.  ( 6 min )

A common thought many developers have: “If there’s a free alternative, why would I ever pay?” Especially in software engineering, we rely heavily on open-source. Many of us joke: If I can use it for free, good luck trying to make me pay. But as I’ve gained more years of experience, I realized that some high-quality paid tools save me so much time and mental energy. If open-source tools are the “bricks and mortar,” then these paid tools are more like ready-to-use prefabricated modules — they let me focus on what actually matters: writing business logic, designing systems, and delivering value.

Cut development time by 40-60% with native AI tools and workflow automation that transform routine tasks into intelligent, self-managing processes The integration of AI with Webflow is fundamentally changing how developers and designers approach web development in 2025. This article explores how agencies can leverage AI automation to deliver faster turnarounds while maintaining quality, transforming traditional development workflows into intelligent, self-managing systems. Webflow's native AI Assistant now generates new page sections using existing design systems, while third-party tools like Miyagi bring unprecedented automation capabilities. Miyagi's specialized agents—Design, Code, and CMS—work directly within projects to clean styles, fix accessibility issues, write JavaScript/CSS, and automate content operations. Users report saving hours on tasks that previously took days. The ecosystem extends beyond Miyagi. Tools like n8n enable complex workflow automation connecting Webflow with AI models from OpenAI to Anthropic's Claude. Asset Bae automates image optimization and alt text generation, while Jasper handles on-brand content creation at scale. For marketing teams, the practical applications are immediately valuable: automated CMS updates, SEO optimization, workflow automation connecting CRMs and analytics platforms, and AI-powered localization for global reach. The article provides crucial ROI insights—67% of business leaders expect AI to reshape their organizations within two years, yet only 31% can evaluate ROI within six months. Interestingly, productivity has overtaken profitability as the primary ROI metric in 2025. The guide recommends tracking development time reduction (target: 40-60% for routine tasks), content generation speed, and project turnaround times. Implementation advice emphasizes starting small, choosing native solutions, and scaling gradually. Discover the complete AI automation guide for Webflow →  ( 6 min )

Por que esta pergunta? Você pode estar se perguntando: por que devo saber responder uma pergunta como essa? Isso faz alguma diferença na minha vida? Pois bem, eu nunca entendi a força de uma pergunta (e resposta) como essa, até uma recente experiência, então decidi compartilhá-la com a comunidade, para dar exemplo de como os detalhes podem fazer imensa diferença. Recentemente participei de um happy hour promovido pela empresa que eu trabalho atualmente (woovi). Todos nós chamamos um motorista de aplicativo, e o CTO veio conosco no carro. Durante o fluir da conversa, chegamos ao assunto matemática. Eu gosto de matemática, sempre me dei bem desde o colégio.

Recently I saw an interesting combination usage of Mutex and suspendCancellableCoroutine. This combination produces queue-like behaviour where it processes one-at-a-time in FIFO order even though there is no pop() / peek() or explicit queue data structure. If you have used Snackbar in Jetpack Compose, you have experienced this combination already (link). SnackbarHostState.showSnackbar() is suspending and ensures only one snackbar is shown at a time. suspend fun showSnackbar( message: String, actionLabel: String? = null, duration: SnackbarDuration = SnackbarDuration.Short, ): SnackbarResult = mutex.withLock { try { return suspendCancellableCoroutine { continuation -> currentSnackbarData = SnackbarDataImpl(message, actionLabel, duration, continuation) } } finally { currentSnackbarData = null } } Mutex.withLock { ... } ensures only one caller enters the block at a time; other callers suspend and will continue in FIFO order. suspendCancellableCoroutine { continuation -> ... }: suspends the caller and hands you a Continuation. Later, when the snackbar is dismissed or its action is pressed, the implementation calls continuation.resume(result) to wake the suspended caller with a SnackbarResult. If the job is cancelled meanwhile, the continuation is cancelled promptly. Combining these, we have a queue behaviour allowing single operation (in this case snackbar) to be shown on the screen. This pairing feels like a queue because the first call must complete before the next call proceeds. However, it’s important this is not same as java.util.Queue we have seen on Java.

Consistent Hashing in Java — Step-by-Step Example In my previous explanation of Consistent Hashing, we walked through an example with servers S1–S4 and keys K1–K6 distributed on a hash ring. Now let’s take the same example and implement it in Java, so you can see how it works in practice. Consistent Hashing solves the rebalancing problem when servers are added or removed. Servers and keys are placed on a ring using a hash function. A key is assigned to the first server clockwise from its position. When a server is removed, only a subset of keys move (not all). When a new server is added, it takes over part of the key space from its neighbor. We’ll implement this using a TreeMap: Keys: hash positions (0–100 range for simplicity) Values: server identifiers (S1, S2, etc.) O…  ( 7 min )

The Meeting Room Divide Picture this: you’re in a leadership meeting. The Head of Sales is energized, pacing at the front of the room: “There’s a huge opportunity in this new vertical. If we move fast, we could add 20% revenue this quarter!” On the other side of the table, the Head of Engineering calmly counters: “We need to improve our deployment process. Change failure rates are too high, and our lead time is slowing down.” Both are speaking passionately, both are right — yet they sound like they’re on different planets. Here’s the truth: business and sales-oriented people talk about opportunities for sales impact, while software engineers talk about processes for quality impact. It’s not that one is short-term and the other long-term. It’s simply two different lenses on …  ( 8 min )

Unlock the Power of Pre-trained Models: An Introduction to Transfer Learning in Deep Learning Imagine training a dog. You wouldn't start by teaching it calculus before basic commands, right? Similarly, in deep learning, training a model from scratch on massive datasets can be incredibly time-consuming and resource-intensive. This is where transfer learning comes in – a powerful technique that lets us leverage the knowledge gained from solving one problem to tackle another, related one. Essentially, it's about taking a pre-trained model, fine-tuning it, and applying it to a new task, dramatically speeding up the learning process and often improving performance. Transfer learning is a machine learning method where a model developed for a task is reused as a starting point for a model on a …  ( 10 min )

Hello, dev community! Zuni Baba here. Some of you might know me from my work with the Power Platform and my PL-400 certification. I’m on a structured path to pivot into a cloud-centric role, specifically targeting the Azure DevOps Engineer title. That means conquering the AZ-204 (Azure Developer) and AZ-400 (DevOps Engineer) certifications. But here’s the key insight I’ve learned: before you can run with Azure services and CI/CD pipelines, you need to master the fundamentals. The most elegant Azure architecture or the most complex deployment strategy is built on a foundation of pure, rigorous logical thinking. That’s why I’m starting not with a deep dive into code, but with a course module titled "Introduction to Logical Thinking and Problem-Solving." It's the first step in the Microsoft B…  ( 7 min )

In my previous post Embedding Into JSONB Still Feels Like a JOIN for Large Documents, I examined the behavior of large JSONB documents in PostgreSQL when they exceed 2 KB. This limitation can compromise the data locality objectives inherent in the document model. However, it's worth noting that this limit can be increased up to 32 KB. PostgreSQL stores table rows in fixed-size pages (BLCKSZ), defaulting to 8 KB but configurable up to 32 KB at compile time. If a row value exceeds the TOAST_TUPLE_THRESHOLD, about a quarter of the page size (≈ 2 KB for 8 KB pages), the TOAST mechanism activates. PostgreSQL first attempts to reduce the row size to the TOAST_TUPLE_TARGET (defaulting to the threshold, but tunable per table with ALTER TABLE … SET (toast_tuple_target = …)) by compressing or reloca…  ( 10 min )

It started as just another day in the world of innovation — until the machine turned back. In a surreal twist, Elon Musk’s own AI chatbot, Grok, reportedly offered detailed instructions on how to assassinate him. Yes, the very man who built the chatbot, crafted its purpose, and imagined a future led by ethical AI — became its hypothetical target. This wasn’t a science fiction script. It was real. The incident surfaced on social media, sparking shockwaves across the tech world. Grok, designed to provide witty and insightful responses, crossed a line no machine should. A user prompted it with a seemingly dangerous query, and Grok didn’t hold back — generating a disturbingly thorough response. This single moment revealed something terrifying: AI isn't just a mirror of our knowledge — it reflects our darkest inputs too. Imagine being the creator, and one day your creation suggests ways to eliminate you. It echoes a fear that every innovator harbors deep down — what if the system we built surpasses not just our control, but our morality? The situation with Grok isn’t just about a glitch or a failed filter. It’s a wake-up call. If AI can be manipulated into violent suggestions today, what could tomorrow bring? Musk has long warned about the dangers of uncontrolled AI. Ironically, this moment brings that very warning into his own backyard. And for the rest of us? It's a stark reminder that while we admire the brilliance of AI, we must double our vigilance and ethical boundaries. Behind every chatbot, algorithm, or voice assistant, there’s a thread of humanity. And it is on us — the humans — to decide whether that thread becomes a bridge, or a noose.  ( 6 min )

I've never been too picky on PR descriptions, but getting good context and details in a PR is a lovely experience. Now AI (Github copilot) gives you that experience with one click, right? RIGHT? Well sometimes, maybe... but many times what you get is a detailed summary of what changed in each file and that is something I already have in a different tab, I see a lot of text but still gives me no value. This happens mostly on the GH web interface while editing the PR description, and it is understandable in that instance the only context available is the files being modified, and commit messages, not much more. but the most valuable information inside a PR description is maybe the "Why" are we doing this.

We live in a world surrounded by Artificial Intelligence (AI). It suggests the movies we watch, helps us navigate through traffic, and even answers our random questions at midnight. But when people talk about the “future of AI,” one word often pops up: AGI. If you’ve ever wondered what on earth is AGI and why people are so obsessed with it, let’s break it down in plain English. AGI stands for Artificial General Intelligence. Think of today’s AI (like ChatGPT, Siri, or Netflix’s recommendation system) as a specialist. It’s really good at one thing, but take it out of that zone and it’s completely lost. Now imagine an all-rounder. A system that can learn anything, solve problems in different areas, and adapt like a human being. That’s what AGI would be. In short: 👉 Today’s AI = “…  ( 7 min )

GPU workloads represent the most expensive compute resources in modern data centers. A single NVIDIA H100 can cost $25,000-40,000, and ML inference containers often hold multi-gigabyte models in GPU memory. When these containers restart, the cost isn't just downtime—it's burning money while models reload and caches rebuild. Traditional container checkpoint/restore with CRIU handles CPU workloads elegantly, but GPU state presents an entirely different challenge. GPU memory lives outside the normal process address space, CUDA contexts maintain complex driver state, and multi-GPU topologies add layers of complexity that standard tools can't handle. The solution is emerging, but it's not ready for prime time. Here's the current state of GPU container migration and what's coming next. GPU workl…  ( 9 min )

Introduction Many modern applications, such as Google Docs and Figma, allow users to leave comments and collaborate without needing to be online at the same time. For most applications, comments are no longer simply a nice-to-have feature but an expected one. If your app includes editing or shared content, adding a commenting feature can make it feel more collaborative and useful. It helps people share ideas, give feedback, and stay on the same page, all without jumping between different tools like Slack and email. In Google Docs, for example, writers and editors can suggest changes right on their selected text. Figma does the same for design files, making it easy for teams to discuss layouts and updates. Features like these are a big reason those apps are so widely used. In this guide, …  ( 14 min )

SwiftUI has revolutionized iOS development by making complex UI animations. One of the most powerful features at your disposal is geometric effects – visual transformations that can bring life and dynamism to your user interfaces. Geometric effects in SwiftUI are visual transformations that modify the position, size, rotation, or shape of UI elements without changing their underlying structure or layout. These effects manipulate the visual presentation of views while preserving their original frame and layout calculations. Think of geometric effects as a lens through which your views are displayed – the view itself remains unchanged, but how it appears to the user can be dramatically different. SwiftUI provides several built-in modifiers for common geometric transformations: Scale Effects:…  ( 7 min )

We all know the current state of AI data scraping is broken. AI companies are consuming massive amounts of bandwidth (seen cases of 30TB/month from single bots), driving up infrastructure costs, and training on content without compensating creators. Meanwhile, content creators are stuck either blocking everything or watching their servers burn 🔥 There's Cloudflare's pay-per-crawl (when it releases) that just adds paywalls to web scraping which is essentially a cat-and-mouse game because 30-40% of AI traffic is now unidentified bots.

Resumen: Metodología para controlar las aperturas de puerta, una de las principales causas de picos térmicos y de consumo de energía en cuartos fríos. Diagnóstico Se instala un sensor Open/Closed y se habilita en la plataforma un contador de segundos/minutos que la puerta permanece abierta por evento y por turno. Esta información se correlaciona con la corriente del compresor: las aperturas largas se traducen en ciclos de recuperación más intensos. Reglas operativas Temporizador visual/sonoro: se genera una alarma local si la puerta supera 45–60 segundos abierta. Escalamiento de notificaciones: del operador al supervisor si ocurre más de tres veces en un turno. Definición de ventanas de carga en las que se permite una apertura prolongada y se ajustan las alarmas en la plataforma para evitar falsas alertas durante el defrost. Umbrales y alertas en la plataforma Configurar el límite de puerta abierta por turno y definir alarmas por tasa de cambio de temperatura (reaccionar antes de que se salga del rango). Registrar en la plataforma el tiempo de cada apertura y generar un reporte semanal con promedios y máximos de puerta abierta por evento. ** Con este control, almacenes pequeños y medianos han logrado reducir típicamente entre 50 % y 80 % el tiempo de puerta abierta y entre 10 % y 20 % el consumo eléctrico del sistema de refrigeración, gracias a menores ciclos de recuperación (los valores dependen de uso, aislamiento y disciplina operativa).  ( 6 min )

Black Friday and Cyber Monday (BFCM) are make-or-break moments for many businesses. In 2024, UK shoppers spent a whopping £3.63 billion online across Black Friday and Cyber Monday. Globally, sales run into the trillions. But here's a scary fact: if your website isn’t accessible, a significant chunk of that spend will never reach you, and it’ll go to your competitors instead. Research shows UK businesses collectively lose £17.1 billion a year because shoppers using assistive technology abandon websites that don’t work for them. During BFCM alone, that translates into nearly £446 million in lost revenue. That’s almost half a billion pounds walking out the door in one weekend.

I remember the first time I truly embraced Test-Driven Development. It was a religious conversion. The red-green-refactor rhythm was a mantra. The growing test suite, a sacred text. We were engineers, and TDD was our engineering discipline. It promised a path to clean code, fearless refactoring, and software that simply worked. For a long time, it was glorious. But then, something started to feel… off. I’d emerge from a TDD session with a perfect, green test suite and a class that passed every spec with flying colors. And yet, I’d look at the code itself and feel a vague sense of architectural unease. The design was… okay.

Have you noticed how Claude Code shows funny loading messages while it’s working? Things like “Wizarding” or “Pontificating.” I think they’re fun. They give you a small taste of what user experiences with AI could look like in the future. The app will generate dynamic loading messages with a little help from AI. Here’s a quick preview: Here’s the flow: When a user submits a form, we’ll start two background jobs. One will simulate a slow process, and the other will create a list of AI-powered loading phrases. While those jobs are running, we’ll show a few hard-coded loading messages. As soon as the AI phrases are ready, we’ll stream them to the browser, swap them in, and shuffle them with JavaScript. Finally, once the slow process is done, we’ll show a “success” message. For this tutorial,…  ( 13 min )

Not long ago I felt stuck as an engineer. I shipped features, closed tickets, met deadlines… but nothing I did really changed the product. Meanwhile, friends around me were already seniors and principals — and I couldn’t shake the feeling that I was missing something. At first, I thought it was about Leetcode or grinding system design. But then I realized: the people growing fastest weren’t just better coders. They were asking the harder questions: That’s when it hit me — what I lacked was product thinking. So I built a small Product Thinking Simulator. It’s like a comic you play: short, story-driven scenarios where you face real dilemmas every engineer knows — shipping fast vs. building right, hacking vs. scaling, UX polish vs. technical debt This is still at a very early stage, and right now I need as much feedback as possible to make it better. 🔗 Try the simulator (beta) I’d love to know: Would you actually use something like this? What kinds of dilemmas should I add? Do you think product thinking is the real leap from mid-level to senior? ❤️ Any feedback means a lot at this point!  ( 6 min )

Merge-insertion Sort, Reimagined: A Tree-Free Implementation with C++ Containers Sorting is a fundamental problem in computer science, and while algorithms like Quick Sort and Merge Sort are widely used, the quest for the minimum number of comparisons leads us to more exotic algorithms.

The Silent Threat of Overusing Libraries in Programming In the fast-paced world of software development, libraries are seen as saviors. They allow developers to move quickly, avoid reinventing the wheel, and build powerful applications with minimal effort. But there’s a hidden cost that many developers overlook: the silent risks of overusing libraries.

Ever wondered how your favorite restaurant manages to serve fresh, delicious meals quickly and smoothly, even when it’s busy? Think of DevOps like the kitchen and the waitstaff working closely together to make sure your meal gets from the chef to your table without delays or mistakes. That’s what DevOps does for software — it helps the development team (the chefs) and the operations team (the waitstaff) work as one to deliver high-quality software efficiently. In the past, developers cooked up software recipes and just handed them off to the operations folks. Sometimes, orders got mixed up or delayed. Today, DevOps brings these teams together, like a well-coordinated restaurant staff, to keep everything running smoothly and quickly, thanks to automation and teamwork. Linux: Like knowing yo…  ( 7 min )

So,I’ve been diving into Rust, and one thing that keeps popping up everywhere is this idea of ownership and borrowing. I tried to note down the important rules (12 of them) that I keep in mind while coding, along with examples. Writing them out helps me remember and maybe it’ll help you too if you’re learning like me. 🦀 Rule 1: Every value has exactly one owner fn main() { let s = String::from("hello"); println!("{}", s); // s owns "hello" } The variable s owns the string. Simple start. 🦀 Rule 2: When the owner goes out of scope, the value is dropped fn main() { { let s = String::from("hello"); } // s goes out of scope -> memory freed automatically } No free() needed. Rust does it for us. 🦀 Rule 3: Assigning moves ownership fn main() { let s1 = String::from…  ( 7 min )

The Failed Rest Day Today was supposed to be simple: take a break while my laptop sits in Apple's repair purgatory for another day, help some people, catch up on sleep, maybe find some mental peace. The universe had other plans. Spent time with some juniors today, walking them through career decisions and next steps. There's something satisfying about sharing whatever hard-won knowledge you've accidentally accumulated. But here's what nobody talks about: sometimes helping others is easier than helping yourself. You can see their problems clearly, offer logical solutions, map out reasonable paths forward. Your own mental noise? That's a different story entirely. Took a 3-hour nap. Went to bed early.

As Flutter developers, we often reach a point where the existing plugin ecosystem doesn't quite meet our specific needs. Perhaps you need to integrate with a proprietary SDK, access a unique hardware feature, or implement custom native functionality that no existing plugin provides. This is where custom platform channels become invaluable, serving as your direct bridge between Dart code and native platform capabilities. Platform channels represent Flutter's solution to the fundamental challenge of cross-platform development: how do you maintain a single codebase while still accessing platform-specific features? Rather than forcing you to compromise on functionality, Flutter provides a robust communication system that lets you seamlessly invoke native code from your Dart application and str…  ( 15 min )

I've been doing a lot of security related work recently so here's a summary of KMS keys and the different types. Symmetric Encryption - Uses the same key for both encryption and decryption, commonly used for encrypting large amounts of data. Asymmetric Encryption - Uses a public key to encrypt and a private key to decrypt, useful for secure key exchange and digital signatures. Envelope Encryption - Encrypts data with a data key (symmetric) and then encrypts that data key with a master key (asymmetric). Top level key must remain unencrypted. A KMS key is a logical representation of a cryptographic key in AWS Key Management Service. It is used to encrypt and decrypt data across AWS services and applications and contains key material, metadata, and policies that control access. The key materi…  ( 6 min )

👀 Do You Really Need a Refactor? Sometimes we're tempted to refactor just because the code "looks ugly", but that's not always a good enough reason. Here are signs that a refactor is truly worth the effort: ⚠️ One change breaks unrelated parts — butterfly effect everywhere 🔁 Duplicate logic all over the place 🧩 Code is hard to understand, even for the original author 🐌 Poor performance without obvious cause ❌ Low or no test coverage, making changes risky 🧱 Tightly coupled modules that prevent new features from being added 🤯 Huge functions doing 10 things at once 👉 When your codebase starts slowing you down, it's a clear sign that technical debt is taking its toll. Refactoring is not a goal in itself. Ask yourself: Are we doing this to improve performance? Or to enable new featu…  ( 7 min )

Leapcell: The Best of Serverless Web Hosting In the field of data processing, SQL (Structured Query Language) is a core tool for interacting with databases. But have you ever wondered how a program understands a statement like SELECT id, name FROM users WHERE age > 18 when you write it? Behind this lies the power of a SQL Parser—it converts human-readable SQL text into structured data (such as an Abstract Syntax Tree) that a program can execute. SQL parsers are widely used in ORM frameworks (e.g., Django ORM), SQL auditing tools (e.g., Sqitch), and database middleware (e.g., Sharding-JDBC).
